A THIRD person has been charged with the murder of a man who was helping friends film a music video.

Detectives charged Devone Pusey, 19, with murder and possessing an offensive weapon after Barking music producer Dean Pascal-Modeste was killed in Lewisham on February 24.

The 21-year-old was unfamiliar with the area and had only travelled to the borough to help friends with a film.

Police were called to Lambscroft Avenue, in Mottingham, at around 3.45pm after reports of a man in possession of a firearm.

Mr Pascal-Modeste was then found lying in the road suffering from stab injuries.

Officers, London Ambulance Service and London's Air Ambulance gave him emergency first aid, but he was pronounced dead at the scene.

Pusey will appear in custody at Bromley Magistrates' Court today (April 10).

Two 17-year-old boys have previously been charged with murder and possessing an offensive weapon.

A trial has been set for Tuesday, August 29, at the Old Bailey.

Detective Inspector Richard Leonard, from the Met's Homicide and Major Crime Command, said: "He had travelled from Barking to Grove Park that day to help friends shoot a music video.

"He has no association with the area and was standing innocently with a friend in Lambscroft Avenue when he was confronted by a group of young men armed with knives and other weapons who chased him into Charlesfield where he was fatally attacked.

"I strongly believe that this was a case of mistaken identity.

"It is a testament to the courage and compassion of the local residents who came to Dean's aid after his attack and attempted to render first aid despite some of the group still being in the area.

"Dean's family are devastated by the loss of a loving son and brother in the most tragic of circumstances.

“He was a young music producer keen to help friends develop their own music careers.”
