Stewart Tendler, London's Times Online Crime Correspondent reports:
Seven teenagers were questioned by police yesterday after a 16-year-old boy was chased by a mob and stabbed to death in a London street lined with £1 million homes.
The murder is the fifth involving black youths in London in the past few weeks.
Witnesses say that teenage girls egged on the attack with shouts of “Kill him, kill him” before the victim, named last night as Kodjo Yenga, was surrounded. At one point Kodjo raised his arms to fend off blows from sticks. The suspects being held include four 13-year-olds, two 15-years-olds and a man aged 21.
