A 22-year-old man who was attacked in Upper Norwood last week was stabbed in the head, police have revealed.

The victim is still in a critical condition after suffering a number of stab wounds. He was taken by London Air Ambulance to a South London Hospital.

Police were called at 4.10pm on Thursday 11 October to reports of a man injured in Brunel Close, Upper Norwood.

The stab wound to the man’s head is potentially life threatening.

Police also confirmed a knife recovered from the scene is undergoing forensic tests. 

Detectives now want to identify a man seen on CCTV shortly before the victim was attacked.

The man is black, in his early twenties, and in the CCTV clip he is seen wearing a green puffer-type jacket, blue jeans and black trainers.

At 4.00pm he is seen walking into Brunel Close, then seen running from Brunel Close a few minutes later onto St Aubyns Road, then through an alleyway onto Church Road.

Detective Inspector Brian Hobbs, Croydon CID, said: “Our victim has suffered very serious injuries and at this stage they are potentially life threatening.

“I am appealing to anyone who recognises the man in the CCTV images to contact the police.

He said: “ I am also appealing to any witnesses who have not yet come forward to do so and help us to piece together the moments just prior to and immediately after the young man was injured.

“I would also like to reassure anyone who is concerned about speaking to the police that they will be treated with the utmost sensitivity.”
