A 19-year-old man has been shot outside an Underground station tonight.

Police swarmed Harrow in north west London after being called to reports of a shooting at 6.40pm.

The young man was found outside Sudbury Hill Station with gunshot wounds.

London Ambulance Service went to the scene and the man was taken to a “major trauma centre” at a hospital.

It is understood he is fighting for life with life-threatening injuries.

A Metropolitan Police spokesman said: “Police were called to Greenford Road, Harrow, at 18:40hrs on Wednesday, 18 November following reports that a man had been shot outside Sudbury Hill Station.

“Officers attended alongside London Ambulance Service.

A London Ambulance Service spokesperson said the 19-year-old was taken to a major trauma centre after an “advanced trauma team” was initially dispatched to the scene, along with other ambulance crews.

The spokesperson said: “We were called at 6:42pm tonight (18 November) to Greenford Road, Sudbury Hill to reports of a shooting.

This is the second tragedy to hit Harrow in the past few days.

Aspiring law student Jamalie Matthew, aged 17, from Harrow, was found stabbed in Northwick Park in the Greater London town, at around 3.50pm on Thursday last week – November 12 – and he died at the scene around 40 minutes later.

Jamalie’s family, said: “The whole family is deeply saddened and utterly devastated about the passing of Jamalie. We all knew of his ambition to study Law, and coming to terms with the tragedy that has unfolded still feels so surreal.”
