A witness has told of the "scene of carnage" after a 17-year-old boy was stabbed to death in a high street in south London.
Police were called to Sutton High Street at about 7.10pm on Tuesday to reports a teenager had been stabbed.
On arrival officers found the boy, suffering with stab wounds.
Despite the efforts of emergency services at the scene near Sutton train station he died as a result of his injuries.
Police said his next of kin have been notified and they are being supported by specialist officers.
A post-mortem examination will be scheduled in due course. A murder investigation has been launched and there have been no arrests.
Det Ch Insp Mike Nolan, who is leading the Met's investigation, said: "This afternoon as Londoners go about their day, a family is reeling from the shock of losing a young family member to violence in our city."
"Our investigation, though in its early stages, is moving at a pace and while we work to establish the circumstances," he added.
A gym goer said: “I’d done a workout then went out into the high street where there were blue lights flashing and a boy on the ground. It was carnage, there were paramedics with equipment and onlookers were in shock. It’s a busy high street there were quite a few people around. There were a group of boys nearby, some had hoods up.”
Restaurant worker Hector Fernandez, 24, said: “I was working but heard shouting and police cars puling up. I looked out and saw people in a panic. Someone told me there was a stabbing and the attacker was on the loose. It’s truly shocking this should happen in the streets of London. I’m originally from Colombia which is very violent. You do not expect this in London. It’s bad for the reputation of this great city.”
A crime scene remained in place in the vicinity of Sutton train station on Wednesday.
The station was closed on Tuesday following the incident, with trains not stopping there.
Police were trawling for clues at the scene of the fatal stabbing.
Specialist teams were carrying out fingertip searches as they hunted for a weapon.
