East Midlands ambulance service contacted police at 8.20pm on Saturday to report that a man had been stabbed on Rose Avenue in the town of Ilkeston.
Arriving at the scene, officers found an 18-year-old man on the road with a stab wound. Emergency services tended to the man but he was pronounced dead on the nearby Heanor Road, Derbyshire police said on Sunday.
