Detectives have released a CCTV image after two train passengers’ phones were swiped from their hands at Brockley rail station.

The thefts took place on March 17 and March 18 when a man snatched two victims’ mobiles and ran from the train as the doors were closing.

British Transport Police (BTP) detectives have released an image of a man they wish to speak to in connection with the thefts.

Detective Constable Oliver Gilbert, of BTP’s robbery squad, said: “On each occasion the passengers were minding their own business when a man snatched their phones from their hand and ran from the train as the doors were closing.

“These thefts were brazen and calculated and I have no doubt that the offender has done this before and will do it again.

“It is vital, therefore, that we speak to the man captured on CCTV as soon as possible as I believe he has vital information about the incidents.”

Anyone who recognises the man or has any information about the thefts is asked to call BTP on 0800 40 50 40 or Crimestoppers, anonymously, on 0800 555 111 and quote log SSUB/B3 of 22/4/14.

DC Gilbert added: “The tactic used by this thief is a classic example of one of the most common methods used by criminals to steal passenger property."
