A blind pensioner was shoved to the floor of a train in an unprovoked attack in south London.
The 80-year-old victim was grabbed by the shoulder and pulled to the floor of a Docklands Light Railway (DLR) carriage shortly before it pulled into Canning Town Station.
The attack took place at around 8.20pm on Thursday, May 1 after the victim boarded the train at Woolwich Arsenal.
The victim was helped to his feet by other passengers and left the train at Canning Town, as did his attacker.
PC Paul Read said: “Thankfully the elderly man wasn’t seriously injured as a result of the assault, but the attack was sudden and unprovoked.
“Enquiries to date have enabled me to isolate the image of a man I believe has vital information about the incident and I urge anyone who witnessed the incident or who recognises the man to contact us.”
