A 15-year-old boy stabbed to death on Thursday has been named by police.

Zaian Aimable-Lina died at the scene of the attack in Ashburton Park, Croydon, south London, shortly after 7.30pm.

The Metropolitan Police said a post-mortem examination gave the cause of death as a stab wound to the heart.

A 15-year-old boy remains in custody on suspicion of murder.

A second fatal stabbing, this time of a 16-year-old boy in Yiewsley, west London, less than an hour later, made 2021 the bloodiest year on record for teenage homicides in London.

Detective Chief Inspector Richard Leonard made a direct appeal for information about the local boy’s death.

He said: ‘My thoughts continue to be with Zaian’s family and friends as they cope with this tragic loss.
