A blind man says he is scared to go out after he was left with a broken jaw following an unprovoked attack at a railway station in Dorset.
Peter Bartlett, 30, was walking home from work when he accidentally bumped into someone at Dorchester station.
He apologised, but shortly afterwards heard someone running up behind him shouting. He was pushed in the back and fell to the floor fracturing his jaw.
British Transport Police is investigating the attack on 15 October.
Police have released CCTV footage in an attempt to identify three men they want to question about the attack.
Mr Bartlett is registered blind after losing his central vision 10 years ago. He can only see slightly out of the corners of his eyes.
He said the assault had left him worried and scared every time he left his house in Dorchester and added he wanted the attacker brought to justice.
He told the BBC: "I can't think of a reason really. I can't get my head around the mentality - people brush past people in the street all the time - no-one acts like that.
"It's not the kind of thing you expect to happen in Dorchester, it's generally a safe place."
"That's why I've tried to raise awareness of this because I want it to stay a safe place. I don't want people thinking that's acceptable."
He said he did not know if his attacker knew he was blind, as he does not walk with a stick.
