Police are searching for a man who left his partially severed diamond-studded ear on the pavement after it was bitten off in a fight.
West Yorkshire Police believe the man did not seek medical treatment after the incident in Huddersfield at about 9.20pm on Sunday night and are urging him to come forward.
A photograph of the ear, complete with the diamond stud earring, has been posted on Twitter but the victim has not yet been traced.
Police said the man fled the scene after the fight between a group of people in King Street.
Two men, aged 37 and 45 and from the Holmfirth area, have been arrested on suspicion of wounding and are currently in police custody.
Police appealed for the injured man and any witnesses to contact them on 101.
