Detectives investigating the death of a man who was found stabbed in the neck on New Year's Day are appealing for a man to come forward.
The area was sealed off for forensic examination
John James Wells, 55, of Doncaster Road, Sandyford, Newcastle, was stabbed at a pelican crossing at the junction between Goldspink Lane and Sandyford Road on Thursday.
Police believe he was stabbed at some time between 2035 GMT and 2050 GMT.
Officers want to trace a man who was seen walking across Goldspink Lane at its junction with Sandyford Road, towards Jesmond Road, at the time.
He is described as being aged around 23, 5 ft 6 in tall, wearing round rimmed glasses and a hat with dark hair underneath, which covered his ears.
He also had a wispy beard and was possibly wearing jeans and a dark blue jacket.
Detective Superintendent Steve Bolam, who is leading the investigation, said: "We are continuing to build a picture of the victim and people that were in the area at time.
"As a result of our enquiries we have a description of a man who was in the area and has a fairly distinctive appearance.
"We believe he may have seen something which could help us and would urge him to come forward.
"We are continuing to appeal generally for any other witnesses, particularly people who saw anybody hanging around in the area in the lead-up to the incident.
"We would ask anybody who lives in the area or was passing by to contact us. We would also urge anyone who has information on who might be responsible for this attack on John Wells to contact the incident room or visit the mobile police station."
