Photo released by police in Normanton murder probe
Police have released a picture of a man who died in hospital after an attack by a gang of about five masked men in Derby.
Officers were called to a fight in Cummings Street, Normanton, at about 1940 BST on Saturday.
Serioza Lawskoski, 29, of Leacroft Road, Peartree, was found in the street unconscious. A post-mortem examination revealed he died of head injuries.
A 25-year-old man has been arrested on suspicion of murder.
He remains in police custody and will continue to be questioned during Monday.
Det Supt Andy Stokes, of Derbyshire Police, said: "It is vitally important that anyone who has information about this murder comes forward to talk to us.
"Mr Lawskoski was attacked in the street in broad daylight and we know that many people saw what happened.
"We'd like to hear from anyone who saw a group of about five men, dressed in black, acting suspiciously either before or after the crime was committed."
Forensic teams who were working in Cummings Street have completed their examination and the road has been reopened, police said.
Officers are continuing to carry out extra patrols in the area.
