Four people - including a teenager on his 18th birthday - have appeared in court charged with the murder of a man in Thetford.
Officers were on patrol on the A134 Brandon Road shortly after 7pm on October 3 when they discovered members of the public providing first aid to a man who had been stabbed.
The man, later identified as David Lawal, was pronounced dead at the scene shortly before 8pm.
A Home Office post mortem examination concluded Mr Lawal, 25, died from a single stab wound to the neck and upper chest.
