Invisible tag for BT cable thieves

Broadband, home phone and digital TV company BT has started fighting back against thieves who take copper network cables and sell the metal as scrap, which leaves areas unconnected and costs the company millions of pounds.
Surging scrap prices led to a 9% rise in cable theft last year, with more than 200 people arrested, and the telecoms giant now uses SmartWater to forensically tag miscreants.
The company's Openreach division uses the invisible solution to mark thieves, as it stays on their skin for up to 60 days.
Bernie Auguste, Openreach head of security, said: "From now on, any criminal who targets the BT network risks being invisibly tagged with SmartWater, meaning the police can trace them, and any stolen cable or equipment, back to the scene of the crime.
"Cable theft affects not only us as a business, but the millions of people who rely on access to phones and broadband across the UK, and with the help of this technology we're fighting back."
Detective Inspector Robin Conway, of British Transport Police, said: "Anyone arrested for metal theft will be examined for traces of SmartWater.
"A search will be made of the person's house and any property, including vehicles with traces of SmartWater on them, is likely to be seized by police."
