This is the face of a sex attacker who pounced on a 36-year-old woman as she walked home after a night out with friends.
Police are continuing to search for the man, who struck in Robert Street, Brighton, last October.
The attacker, described by police as "dishevelled and smelly", grabbed her before assaulting her.
Detective Constable Dick Bidmead, investigating, said: "The victim was deeply shocked by her ordeal and she is still upset today."
The attacker is about 25 to 30 and is possibly a vagrant or beggar.
Anyone with information should call Brighton CID on 0845 6070 999 or Crimestoppers on 0800 555 111.
