A teenager has been stabbed to death in a fight during the morning school run in west London.
Police found a 15-year-old boy suffering from multiple stab wounds after being called to reports of a fight on Blyth Road in Hayes at around 8.30am today.
The victim died at the scene. A suspect had been detained, said the Metropolitan Police, but provided no further details.
Formal identification of the victim has yet to take place and a post-mortem examination will be held in due course, the force added.

It follows seven people being arrested following the fatal stabbing of another teenager in south London yesterday afternoon.
