British Transport Police (BTP) has implemented extra protection for railway sites, including helicopter surveillance and CCTV. The increase is due to a rise in thefts of copper and other metals. The BTP has set up a dedicated task force with increased patrols, working in partnership with other interested bodies. Assistant Chief Constable Alan Pacey said: "We are working to tackle the issue and in the past few months have seen significant jail sentences handed down to cable thieves put before the courts.”
