A teenager has been arrested on suspicion of stabbing a 16-year-old to death on a Tyneside street.
Police family liaison officers are with Mark Smith's parents
Mark Smith, of St Johns Walk, Newcastle was found with a knife wound to the neck in the West End of the city on Wednesday. He later died in hospital.
Police said a 16-year-old boy had been arrested on suspicion of Mark's murder and was in custody.
They also confirmed they were investigating reports of an altercation around Gill Street before the death.
It is believed Mark made his way, after being wounded, through Axbridge Gardens to Elswick Road, where he collapsed.
He was later found on the corner of Elswick Road and Caroline Street.
Police are carrying out a detailed forensic examination of the scene
Det Ch Insp Roger Ford, who is leading the investigation, said: "We believe that at the time this happened, there were a number of people in the area and I have no doubt that members of the public who were walking, driving or living in the area would have seen or heard something.
"Knife crime is completely unacceptable and it's vital that people come forward with information.
"Our thoughts and sympathy go out to Mark's family at this time.
"Trained family liaison officers are with his parents who are working with us to help us progress this investigation."
On Thursday evening a post-mortem examination concluded that the 16-year-old died from a single stab wound to the neck.
Elswick Road has now been re-opened on the northbound carriageway.
Traffic lights are in place on the southbound carriageway.
