A TEEN has been arrested on suspicion of murder after a 15-year-old boy was stabbed to death in London's bloodiest year ever.

Emergency crews were rushed to Croydon, South London, last night after the horror unfolded.

Sadly the teen couldn't be saved and was declared dead at the scene.

Police have now confirmed a 15-year-old boy has been arrested on suspicion of murder and remains in custody.

The teen's death came less than an hour before a 16-year-old boy was knifed to death in Hillingdon, West London.

The Met said there is nothing to link the two murders but urged parents to talk to their children about carrying weapons.

Police Commander Alex Murray, in a direct appeal to parents from the scene in Croydon, said: "If you have concerns, talk to your kids.

"Make sure they're not carrying knives, make sure they're not hanging around with kids carrying knives.

"We don't know who has knives but we can find out and we can stop them hurting someone or being hurt."

The double killing came as London was gripped by its bloodiest ever murder epidemic.

There have been 30 teenagers killed in the capital during a deadly 12 months.

In 2020 there were 17 young people murdered, 25 in 2019, 24 during 2018 in London and 27 in 2017.

The youngest to die this year was 14-year-old Jermaine Cools, who had been walking with a relative when he suffered stab wounds on November 18.

Of the teenagers killed this year, the majority – 27 – were stabbed. Two were shot and one died in a suspicious house fire.

Figures show violence fell by more than a quarter during lockdown in London. However, the number of murders has increased.

Earlier this year the Met launched a “surge” of officers onto the streets in a bit to stop the rising tide of violence.
