POLICE are keen to catch a thug who punched a man with hearing difficulties on his way home from work.

The 25 year-old victim's hearing aid was knocked out, and he may have suffered permanent ear damage in the unprovoked assault.

He was struck after asking the man, who was pestering him and whom he suspected of being drunk, to leave him alone as he walked along Long Lane from Hillingdon Tube station in the early hours of March 1.

Police have not made an arrest in the six weeks since the assault, so have appealed, to jog the public's memory.

The attacker was white, aged between 40 and 60 years old, with short white hair and stubble. He was wearing a white hooded top.

Anyone with information should call Detective Constable Emma Thomson at West Drayton Community Safety Unit on 020 8246 1766. Alternatively, call Crimestoppers on 0800 555 111.
