Police have launched a murder hunt after a man was attacked in a launderette in Exeter.
Police say there is no evidence a weapon was used in the attack
The victim, who has not been named, died in hospital after the assault on Tuesday night at the Silverspin Launderette in Blackboy Road.
Witnesses who alerted the police said the victim suffered "several blows" in the incident.
Detectives want to talk to a man in his 30s with bleached blond hair styled in three-inch spikes.
He is said to be about 6ft and was wearing a round-neck T-shirt.
More than 60 officers from Devon & Cornwall Police are involved in the inquiry.
Det Insp Ken Lamont said officers would be examining CCTV footage and a thorough analysis of the scene would be carried out.
Mr Lamont asked members of the public who were in the Blackboy Road area between 2000 BST and 2145 BST to contact police.
He urged the attacker to come forward. "He may not know the consequences of his actions and might not know the victim had died", said Mr Lamont.
There was no one else in the launderette at the time, and there was no evidence of a weapon being used.
