Police have revisited the scene of a “brutal, pre-meditated murder” in Northolt a week after a teenager was found dying on a street.

Jason Isaacs was discovered in Newnham Close suffering multiples stab wounds at around 10.30pm on November 18.

He was taken to a London hospital where he died on Tuesday (November 21).

Officers were in the Newnham Close and Oldfield Circus area between 10pm and 11.30pm on Saturday (November 25) hoping to speak with people who were in the area at the time of the incident.

Appeal posters are also being handed out in the area.

It follows a post-mortem examination on Friday (November 24) which found Mr Isaacs’ cause of death to be a stab wound.

Police say the four male suspects arrived on the scene on two mopeds, and could be responsible for other offences.

Detective Chief Inspector Noel McHugh said: “This was a brutal, pre-meditated murder. The attack was ferocious and clearly intended to deliver fatal injuries.

“Those responsible for Jason’s death were riding two mopeds, both will pillion passengers – we need your help, who were the attackers?

“Did you see them riding around the area before the attack? The pillions were not wearing crash helmets so they would have stood out? Have you seen them in the days before the attack?"

DCI McHugh added: “It has been suggested that these males may have committed other crimes, such as robberies or assaults.

“If you have been chased, robbed or hurt by the group please make contact with my incident room. I will deal with your information confidentially.

“What you may believe to be insignificant, could be very important to our investigation.”

On Friday (November 24), a £20,000 reward was also offered for any information surrounding the fatal stabbing.

Appealing to the local community to come forward with information, DCI McHugh continued: “I know there are people who know who the suspects are.

"It is vital that we hear from those people without delay.

“I would ask that the appeal leaflet be distributed as widely as possible to ensure that anyone who may be hesitating to contact police has a direct line to assist the investigation.

“A young man has lost his life and I sincerely hope that the local community will support the appeal to identify those who took his future from him and help us remove these dangerous individuals from your community.”
