Two more teenagers arrested over murder of 18-year-old Jason Isaacs in Northolt

Two more teenagers have been arrested on suspicion of the murder of an 18-year-old apprentice carpenter stabbed to death in north London.

Jason Isaacs, described as "amazing" and "beautiful", was found critically injured in Newnham Close, Northolt, on the evening of November 18.

The teenager was rushed to hospital where he died three days later.

An 18-year-old man, from Watford, and a 16-year-old boy, from north-west London, were arrested at their home addresses on suspicion of murder on Tuesday morning, Scotland Yard said.

The older suspect has been released under investigation, while the youngster remains in custody in a north London police station.

It comes after the arrest of a 17-year-old boy on November 30 who was subsequently charged with murder.

Detective Chief Inspector Noel McHugh said: "It has been three weeks since Jason was attacked and killed.

"We have charged one male and made two further arrests, but we continue to appeal for anyone who witnessed the attack, or anyone with information to come forward.

"Our suspects are four people riding on two mopeds. At least one of them was not wearing a crash helmet."

A post-mortem examination determined Mr Isaacs, who was from Northolt, died of a stab wound.

A £20,000 reward has been offered by police for any information that could lead to the prosecution of the teen's killers.

His mother Sharon Kendall said: "Our amazing, beautiful Jason went out with friends for a night out and a few drinks. He should have come home to his loving family.

"Our lives are in pieces. Every little piece of information is really important. For Jason, make that call, thank you."

The charged teen is due to appear at the Old Bailey on February 20, with a provisional trial date set for April 30.

Anyone with information is asked to call police on 020 8785 8099 or Crimestoppers anonymously on 0800 555111.
