A third teenager has been arrested on suspicion of murder one week on from the stabbing of Jamil Palmer in Hanworth.

Detectives investigating the murder arrested a boy, believed to be 15-years-old, yesterday (Tuesday).

He has been remanded in custody.

Previously an 18-year-old man and a 16-year-old boy were arrested on suspicion of murder and have been bailed pending further enquiries, returning to a date in early June.

Detectives continue to appeal for witnesses to come following the incident at Crane Park, near Evans Grove, on Tuesday, May 6.

The investigation is being led by detective chief inspector Noel McHugh, of homicide and major crime command, who has stated 'misguided loyalty' is deterring people from coming forward.

Mr McHugh said: "It is clear that there is a misguided loyalty where some people are not speaking to the police, protecting those involved.

"I would ask those who are reluctant to come forward to do so, so Jamil and family can get the justice they deserve."

Detectives have said they will protect witnesses and are appealing to dog walkers and other park users who may have been in the area to report to the police.

18 year old stabbed to death in Crane Park Hanworth TW13
 

Jamil, 18, of Belgrade Road, Hampton, was at a friend's house in Butts Farm Estate which he left around 3.15pm and was attacked around 3.30pm.

He was airlifted by air ambulance to hospital where he later died.

Jamil's mother [unnamed] said: "Do the right thing in Jamil's memory. Forget your street code, it is not grassing and it is not cool. Just tell the police what happened and who was involved.

"I've lost my son. The hurt that has been caused is unimaginable."

A post-mortem examination gave the cause of death as a stab wound.
