The stabbing is thought to have taken place at around 4.40pm on Saturday
A 19-year-old is fighting for his life after he was stabbed in the chest while on a bus in north London.
Police were called to reports of a stabbing on the 134 bus in the North Finchley area at around 4.40 in the afternoon on Saturday.
Paramedics treated the teenager for a stab wound near Colney Hatch Lane before he was airlifted to an east London hospital.
He remains in a critical condition, a police spokesperson has said, also confirming that no arrests have yet been made.
Anyone with information is asked to call Barnet CID on 101, quoting reference 5259/9MAR. Alternatively, they can Tweet @MetCC or call Crimestoppers anonymously on 0800 555 111.
This latest stabbing comes as concerns grow over a rise in knife crime in London, with five fatal stabbings in the last week alone. Only last week, a 17-year-old died after being stabbed in Havering in the east of the city.
Theresa May recently dismissed suggestions that the increase in stabbings could be linked to the reductions in police numbers.
In a bid to help tackle the growing problem, it was suggested earlier in the week that the army could be used to support police forces.
