A murder investigation has been launched after a teenager was stabbed to death in London.
Police and ambulance services were called to Raleigh Road, Southall, shortly after 9pm on Wednesday.
A boy, believed to be aged 16, was found with stab wounds and despite the efforts of paramedics he died at the scene a short time later.
The Metropolitan Police said his next of kin had been informed and that formal identification was now due to take place.
Homicide detectives have been informed of the killing but no arrests have yet been made, the force said.
The boy is believed to be the 28th teenager murdered so far this year in London.
There are fears the capital could be on track to surpass the highest number currently on record, which was 29 in 2008.
Anyone with information on the murder is asked to call police on 101 or tweet @MetCC and quote CAD 7200/24Nov.
