‘fingerprint’ tracking method

In a discovery that could help law enforcement agencies across the globe track 3D-printed guns and counterfeit goods, a team of scientists at the University at Buffalo has found that no two 3D printers are the same, and that all have their own “fingerprints”.

The researchers claim to have developed what they describe as the world’s first accurate method for tracing a 3D-printed object to the device on which it was made.

Commenting on the discovery, study lead author Wenyao Xu said:”3D printing has many wonderful uses, but it’s also a counterfeiter’s dream. Even more concerning, it has the potential to make firearms more readily available to people who are not allowed to possess them.

“3D printers are built to be the same. But there are slight variations in their hardware created during the manufacturing process that lead to unique, inevitable and unchangeable patterns in every object they print.”

Xu and his team found that every layer of a 3D-printed object contains unique tiny wrinkles that can be used to identify various characteristics of the machine that was used to create it, including printer model type, filament, nozzle size and other factors.

To test their new tracking method, which they dubbed the PrinTracker project, the scientists printed five door keys from 14 common 3D printers.

They then scanned each of the door keys to create a digital image that was enhanced and filtered, allowing for the identification of the unique in-fill patterns of each object.

The researchers were then able to match each key to the printer on which it was produced with 99.8% accuracy.

Xu likened the tracking method to the ability to identify the source of paper documents, a practice that has been used by law enforcement agencies, printer companies and other organisations for decades.

Speaking with Vice News, David Chipman, Senior Policy Adviser at Giffords Law Center to Prevent Gun Violence, said: “For this to be useful to law enforcement who would be tracing guns, you’d have to have a record of the unique signature of every 3D printer being sold. We can only match it if we already have a record of it.”

While 3D-printed guns are currently widely considered as being flimsy and unreliable, experts fear that as the technology advances, they could be routinely used by criminals and terrorists on account of the fact they were considered to be nearly impossible to trace.

cannabis bricks in bogus baby belly

Law enforcement officers in Argentina have arrested a woman close to the South American country’s border with Chile for attempting to smuggle cannabis concealed inside a fake baby bump.

The woman was searched after police discovered that her travelling companion was in possession of a smaller quantity of cannabis while the pair were on a long-distance coach journey from the city of Mendoza to Caleta Olivia in province of Santa Cruz.

After stopping the pair at a police checkpoint in Valle de Uco close to Mendoza, police found that the woman had hidden 15 packages of cannabis in her bogus baby bump.

The man with whom she was travelling was discovered to be in possession of two packages of the drug in his hand luggage.

Police stopped the pair while conducting routine checks on passengers using the coach route.

In total, the woman and the man were found to be carrying in excess of 4.5kgs of cannabis.

The improvised fake pregnancy bump was held together with a starch-based paste and secured to the woman’s stomach to make it appear as though she was with child.

Posting a picture of the fake baby belly on Twitter, Argentine security minister Patricia Bullrich told her followers: “She made a belly with glue, and hid 15 packages of marijuana inside it while pretending to be pregnant and attempted to move it from Mendoza to Santa Cruz .

“Police arrested the false pregnant woman and her accomplice, preventing her from trafficking the drugs she was carrying.”

In a statement, Argentine police said: “While carrying out control checks, officers stopped a group travelling from Mendoza to Caleta Olivia.

“During the inspection, police observed that a passenger was carrying a black bag that contained two brick-like packages.

“Continuing with their inspection, officers came across a young woman who had a lump in her belly, pretending to be pregnant.

“The two passengers were asked to get off the bus and were later arrested.”

In September 2013, the BBC reported that police in Colombia had arrested a Canadian woman when she attempted to board a flight to Toronto while wearing a fake baby belly that was filled with cocaine.

Police said the woman was searched after she became agitated when asked by a customs officer how far along she was with her pregnancy.

She was found be carrying two sealed bags that contained 2kgs of cocaine.

Lithuanian and Spanish police smash violent sex trafficking gang

A joint operation carried out by law enforcement agencies from Lithuania and Spain has resulted in the break-up of an organised crime network that trafficked women for the purposes of prostitution.

In a day of action coordinated by investigators from both countries, and supported by Europol and Eurojust, 50 searches were conducted at several locations across the two nations, resulting in the seizure of a quantity of cash, drugs, counterfeit documents, weapons and ammunition.

The operation also saw the detention of two leaders of the criminal network in Spain, the arrest of 13 suspected members of the gang in Lithuania, and the identification of 118 suspected trafficking victims from a number of countries including Ukraine and Belarus.

In a statement, Lietuvos Policija said the effort was the result of a two-year investigation into the illegal activities of the trafficking network, which is said to have used extreme violence to force victims to work as prostitutes in Lithuania.

Those arrested are said to have previously been convicted of a range of offences, including robbery, human trafficking, profiting from prostitution, and criminal damage.

All of those held, who were taken into custody where they are currently awaiting trail, have had their assets temporarily frozen.

“Europol supported the investigation by providing coordination and analytical support since the early stages of the joint investigation in 2018,” Europol said.

“Europol supported the action day by providing on-the-spot technical and analytical support in Lithuania and Spain, and by activating the virtual command post to speed up operational information exchange.

“Europol also deployed experts to Lithuania to cross-check operational information in real-time against Europol’s databases.”

Last week, four members of an eastern European sex trafficking gang were jailed for a total of over 36 years for smuggling Slovakian women to Scotland and forcing them into sham marriages, slavery or prostitution.

Vojtech Gombar, Anil Wagle, Jana Sandorova and Ratislav Adam were convicted in October of what the High Court in Edinburgh was told were “utterly repugnant” crimes.

Back in February, a pair of brothers from Romania who trafficked women into Spain before forcing them to work as prostitutes were handed jail terms totalling 108 years.

A Spanish court heard Cristian and Sebastián Sandulache, who were said to have made as much as €11,000 ($12,096) a night by forcing their victims to sell sex, inserted metal balls into their penises in order to cause maximum pain to their rape victims.

Dutch trucker charged with drug trafficking after UK customs find huge haul of cocaine wrapped in frozen meat

cocaine wrapped in frozen meat

Officers from the UK’s National Crime Agency (NCA) have charged a Dutch truck driver with attempting to smuggle cocaine worth an estimated £20 million ($25.7 million) into Britain while it was hidden in frozen meat.

The agency, which is often referred to as the UK’s equivalent of the FBI, launched an investigation after customs officers stopped the driver’s truck when it arrived at Harwich International Port in Essex on a ferry from the Hook of Holland on Monday.

While inspecting the load the truck was carrying, investigators discovered multiple packages containing a total of over 200kgs of cocaine that had been wrapped in frozen meat.

The driver, named as 48-year-old Robert Tromp from the Netherlands, was charged with an importation offence, and appeared before Colchester magistrates on Tuesday, where he was remanded in custody until his next appearance at Chelmsford Crown Court on 12 December.

Commenting on Tromp’s arrest, NCA Branch Commander Jacque Beer said: “While forensic checks are still being carried out on this seizure, it is likely that the total haul would have had a street value in excess of £20 million once cut and sold at a street purity level.

“Our investigation into those responsible is continuing, but we can say that this will have put a big dent in the profits of the criminal network likely to be behind it and caused them substantial disruption.

“The illicit drug trade is a key driver behind the gang violence and exploitation we see on UK streets, which is why we, along with partners like Border Force, are determined to do all we can to stop drugs at source and protect the public. This was an excellent detection by our Border Force colleagues.”

Drug traffickers routinely hide their illicit shipments in consignments of food, not least on account of the fact that perishable goods are often fast-tracked through customs checks.

At the end of last month, two drug traffickers from the Netherlands were jailed for a total of more than 11 years by a UK court for attempting to smuggle more than half a tonne of cannabis into Britain by hiding it in consignments of grated pizza cheese and salad.

Dominic Leema and Henrik Ruben were caught after trying to smuggle the drugs through the port of Dover in the south of England, and were said to have been part of a wider organised crime network that used an industrial estate unit to extract the cannabis from the cheese.
