A Cypriot student is facing a possible jail term after admitting taking eight explosive flares on to a plane at Stansted Airport and possessing a terrorist manual.
22-year-old Andreas Pierides from Finchley, London was stopped on the gangway as he was about to board a flight to Cyprus on 15 May.
Police were alerted to Pierides after a member of the public spotted him on a train reading an electronic publication with instructions on how to make a car bomb on 19 January.
As they arrested him, officers seized a box of distress signal mini-flares which they found inside luggage which had already been stowed on the plane, a court heard.
But they handed them back in error after Pierides was charged for having a terrorist manual.
Five days later, police went to his bail address in north London to ask for the flares back and arrest him again, this time under the Aviation Security Act 1982.
At a hearing at the Old Bailey, Pierides pleaded guilty to a charge under the 2000 Terrorism Act of possessing an electronic version of the Anarchist Cookbook, he also admitted having a dangerous article in an airport.
The judge Mr Justice Sweeney ordered a pre-sentence report and adjourned sentencing to 27 October.
Border Force officers at Stansted Airport have seized counterfeit “Disney” children’s clothing and accessories worth more than £10,000.
The dresses and bags arrived at Stansted from China earlier this month.
Officers discovered 490 dresses and three bags carrying images of the popular Disney ‘Frozen’ film.
An investigation was launched by Border Force’s International Trade Team which specialises in recognising counterfeit products and works with the owners of big brands to establish whether or not goods are genuine.
Disney have confirmed that all of the goods are counterfeit and they will now be destroyed.
As the rights holders, Disney can now decide whether or not they wish to prosecute the importer privately.
Everyone loves a bargain, but if the price appears too good to be true, either at a car boot sale, a market stall or online, it probably is.
The international trade in counterfeit goods is linked to serious and organised crime and undercuts honest traders, damaging our economy.
Anyone who has been sold counterfeit goods or knows someone who is selling them should contact Action Fraud on 0300 123 2040.
