A man who was stabbed to death in south London has been named as Kye Manning.

Emergency services were called at about 9.10pm on Thursday to Croydon following reports of a stabbing. Manning, 19, was pronounced dead at the scene about 40 minutes later, Scotland Yard said.

A postmortem examination identified the cause of death as a single stab wound to the heart.

Police said five males had been arrested as part of the investigation. An 18-year-old man who was found nearby with stab injuries was arrested on suspicion of murder and remains in hospital.

A 20-year-old man who was found close to Purley railway station with a slash wound was arrested on suspicion of murder and remains in hospital.

A 17-year-old boy was arrested near the scene on suspicion of murder and an 18-year-old man was arrested near the scene on suspicion of attempted murder.

A 15-year-old boy was also arrested near the scene on suspicion of murder and released on bail to a date in early August pending further inquiries.

DCI John Massey, who is leading the investigation, said: “This is a terrible incident which has resulted in a young man’s life being tragically cut short. Our thoughts are with his family and friends at this very difficult time.

“We have made a number of arrests, and my officers and I will continue to work tirelessly to piece together what happened and to bring those responsible to justice.

“However, we cannot do this alone and I would call on the community to help us solve this heinous crime.

“I would urge anyone who witnessed what took place or anyone with information about those responsible to contact police immediately.”
