Detectives are appealing for help in identifying a man who left a  college student blind after throwing a corrosive liquid in his face.

Two victims, aged 19 and 25-year-old, were injured in the attack which happened a month ago on Monday 7 December 7, at 8.10am as they walked on Thornton Road near to the junction with Gonville Road (pictured).
They were approached by the suspect, who was unknown to them and he threw a cup of corrosive liquid over them both before running away.
Both victims were hospitalised following the attack, with the 19-year-old suffering from permanent loss of sight. He had been walking to college when the attacker struck.
During his statement to police, one of the victims said that the same man had turned up at his home address in Thornton Heath in September, prior to the incident, claiming to have a letter for him. When the victim proceeded to collect the letter, the man punched him in the face with a bicycle chain wrapped around his fist.
No CCTV has been identified and at this stage the identity of the attacker and the motive behind the incident remain unknown. Police want to speak to the man pictured in connection with the attack.
The suspect is described as a white or Asian man in his 30’s with a slim build. At the time of the attack he was wearing a blue medical mask, a long black jacket with the hood up, black trousers and shoes.
