Sex assaults on the DLR that saw two women groped are among crimes being targeted in a police crackdown across the transport network.
In the first attack a man inappropriately touched a woman while they were travelling between Pontoon Dock and Canning Town on Sunday, August 30, at 11.04pm. The attacker left the train at the latter station.
Both appeals form part of a wider British Transport Police crackdown on sexual assault on the transport network.
Detective Superintendent Richard Mann said: “Our message is clear – passengers who experience unwanted sexual behaviour will be believed and taken seriously.
“We are just as clear in our message to potential offenders and suspects that we will tackle the problem and fully investigate reports.”
Anyone with any information on the appeals should call police on 0800 40 50 40.
Meanwhile, crime on London’s transport network has fallen for the ninth year running.
