Two schoolboys have been arrested over the murder of a teenager on a busy high street.
Yemurai Kanyangarara, 16, was stabbed in the neck seconds after getting off a bus in what police suspected was a feud between individuals from two schools.
Detectives described the murder in Welling, south-east London, as one of the most brutal they had seen in 25 years.
A 15-year-old boy from Peckham and a 14-year-old boy from Camberwell were arrested on suspicion of murder this morning, said Scotland Yard.
One witness said he watched the boy's life "slip away" as he lay on the pavement on Upper Wickham Lane. The victim came from nearby Belvedere.
Yemurai's father Kelton left a message on his Facebook page that read: "My boy is gone it is so painful - my heart is bleeding. RIP my boy I will always love you."
Detective Chief Inspector Mark Dunne told reporters: "You've got someone 16 years old, a schoolboy, being stabbed in broad daylight in a busy street in front of many, many shoppers out enjoying the afternoon. It's about as bad as it gets.
"It's among the very worst I've investigated in 25 years, the sheer brutality against a defenceless schoolboy."
The victim, who came to Britain from Zimbabwe when he was a toddler, stepped off a 96 bus with a friend and was attacked, probably within a matter of seconds, during the Friday rush hour.
The victim was a pupil at St Columba's Catholic Boys' School in Bexleyheath and had recently finished his GCSEs.
