A 17-year-old has been left with potentially life-changing injuries after being followed and stabbed during a violent attack near a north London Tube station.
The teenager was targeted on Sunday evening by an unknown man and woman who followed him after he left West Hampstead Tube station at around 5.54pm, Scotland Yard said.
He then became involved in a fight with two suspects in West End Lane before being stabbed, which left him with “very serious and potentially life-changing injuries” to his arm.
The unidentified pair are then said to have fled the scene before re-entering West Hampstead station without paying.
Police have now launched an appeal for any witnesses who saw the “violent attack” to come forward and help with the investigation.
Detective Constable Rob Griffiths, from CID at the Central North Operational Command Unit in Islington and Camden, said they have no evidence to suggest the attack was gang-related.
He said: “This is a violent attack in which the victim has received very serious and potentially life-changing injuries. The motive for this attack is not yet known.
“We do not know if the victim and suspects were known to each other beforehand, or they met just prior to the attack.
"I am appealing for anyone with information to get in touch with police and provide us with any details they may have, however insignificant they might seem.
“We would particularly like to speak to a female witness, who we believe approached officers at the crime scene originally and could have vital information that might help progress our investigation.
"If you are this woman, we would ask you to please contact us again as soon as possible."
No arrests have been made and an investigation continues.
Anyone with information is asked to contact police on 101 and quote CAD 6012/28Oct or call Crimestoppers anonymously on 0800 555 111.
