Police have condemned the actions of a man who attacked and robbed a disabled man at Diss rail station.

British Transport Police officers are appealing for information after the 28-year-old victim, who has cerebral palsy, was targeted whilst standing on the platform on Tuesday, June 14.

Detectives have also released a CCTV image of a man they would like to talk to in connection with the incident which took place shortly after midnight.

Det Sgt Dave Strange said the victim was first approached by the man onboard the 11.23pm National Express East Anglia service from Colchester to Diss.

Both men got off the train at Diss and the offender appeared to leave the station, but returned a few minutes later and struck him on the back of the head with a brick, knocking him unconscious.

When the victim came round, he discovered that �80 cash had been taken from him. A member of the public helped him report the incident to police and he was taken to Broomfield hospital in Chelmsford for treatment.

Investigators believe the robber may have links to both the Ipswich and Colchester areas.

DS Strange said: 'This type of incident is very rare on the rail network and that is part of the reason why I'm treating it so seriously. The victim was clearly vulnerable, and his attacker would have known this having previously spoken to and befriended him on the train.'

'I am now urging anyone who recognises the man, or has information about the incident, to contact us immediately.'

Anyone with information is asked to contact British Transport Police on 0800 405 040 or call Crimestoppers anonymously on 0800 555 111.
