A teenager has been charged with the murder of Milton Hurlington, who was fatally stabbed in Wembley 10 days ago.
Wael Farroukh, 18, of Llanover Road, Wembley was charged with Mr Hurlington’s murder on Thursday, along with possession of an offensive weapon.
He was due to appear in custody at Willesden Magistrates’ Court the same day.
Eight other people have been arrested in connection with the investigation, which Scotland Yard said “remains ongoing”.
Police, paramedics, and an air ambulance were scrambled to The Dene in Wembley around 9.50pm on July 17, to reports a man had been stabbed.
Mr Hurlington is believed to have been attacked in King Edward VII Park, before staggering to The Dene where paramedics tried to save his life.
The 42-year-old died at the scene despite their efforts.
A post-mortem examination established his cause of death as blood loss following a stab wound to the arm.
DCI Linda Bradley previously said: “We believe Milton was attacked in King Edward VII Park and then made his way to The Dene, where residents discovered him and called the emergency services.
“I remain keen to hear from anyone who saw or heard anything out of the ordinary in the park and surrounding areas on Monday, July 17 between 6pm and 10.45pm to come forward.
“Please do not hesitate to get in touch, no matter how insignificant you may think your information to be- it could be the key to our investigation.”
A “significant” £20,000 reward is being offered by the independent charity Crimestoppers, for information that leads to the arrest and conviction of those responsible for Mr Hurlington’s murder.
DCI Bradley said: “To be eligible for that reward you need to contact them. Crimestoppers is independent from the police; you can provide information anonymously via 0800 555 111 or through their website.”
The Met’s Directorate of Professional Standards has been informed of the death as officers had been in contact earlier in the day with Mr Hurlington.
