Murder investigation launched in Sheffield
A murder inquiry is underway following the death of an 18 year old man in the Norfolk Park area of Sheffield on New Year’s Day.
Emergency services were called to St Aidens Road at around 4.20am this morning (1 January) following reports of a fight between a group of men. Officers arriving at the scene discovered the young man who had suffered stab wounds.
He was taken to hospital but sadly died a short time later. His family have been informed and are being supported by specialist officers. Formal ID has not yet taken place.
Three men, two aged 18 and one aged 20, have since been arrested on suspicion of murder and remain in custody at this time.
There remains a police presence in the area this evening.
Enquiries are underway and anyone with information is being urged to call 101 quoting incident number 458 of 1 January 2020.
