A police investigation launched in the aftermath of a fatal triple stabbing is continuing after a man arrested on suspicion of murder was released.

Officers were called to Elthorne Road in Archway, Islington, at 11.33pm on June 29 after three people were stabbed.

Two victims, including 15-year-old Leonardo Reid, subsequently died from their injuries, while another man remains in hospital.

A 46-year-old man was arrested on suspicion of murder and attempted murder on Saturday (July 1).

He was taken to a north London police station but subsequently released “with no further action” taken.

Police have now renewed their call for witnesses to come forward so that the families of the victims get the answers they "so desperately need".

When police responded to reports of a stabbing in Elthorne Road last week, they found 15-year-old Leonardo Reid at the scene.

He was treated for stab wounds by paramedics but died in the Archway street shortly after midnight.

A second victim, described as a 23-year-old man, was rushed to a west London hospital where he was later pronounced dead.

A post-mortem examination for both victims gave a provisional cause of death as a stab wound to the chest.

A 28-year-old man was also found in the Archway area suffering from a stab wound.

He remains in a north London hospital where his condition was described by police as “not life-threatening”.

Renewing the police appeal for information about the incident, Detective Chief Inspector Jim Eastwood, said“We’re three days into our investigation, and whilst enquiries are ongoing, I still need to hear from anyone who was in the vicinity of Elthorne Road on Thursday night.

“Two people have lost their lives through an act of violence and it is vital that we get the answers their families so desperately need.

“I know that there are people who are yet to come forward. I would ask that you consider the feelings of those whose lives have been impacted upon by these senseless murders and make contact with us."
