Police have identified a man they wish to speak to in connection with a series of defibrillator thefts at train stations.

The British Transport Police (BTP) appeal follows incidents at Woodford and Leytonstone stations on Tuesday, April 5, at 12.55am and 5.40am respectively.

Other incidents took place at Bow Road, Loughton and Stratford stations on Saturday, April 2, at 1pm, 3pm and 10.15pm respectively.

Police say a man approached the defibrillator cabinet at the stations, opened it up and took the defibrillator out on each occasion.

He then either placed it into a bag or under his jacket and left.

Investigating officer Det Con Angie Gates said: “We believe that all five incidents are linked and I am keen to speak to anyone who may hold information or knows the person in the CCTV image, who I am keen to speak to and who I believe has information that could help us.

“Defibrillators can save lives and it’s really disappointing that these have been stolen.”

Anyone with any information can call BTP on 0800 40 50 40 or text 61016 quoting reference 349 10/06/2016.
