Police are now appealing for information and witnesses to come forward to help with their murder investigation.

Detective Chief Inspector Noel McHugh of the Homicide and Major Crime Command said: "Firstly I would like to hear from anyone who saw the mint green Vauxhall Corsa on the Turnham Estate prior to the collision.

"Several people rushed to help Nassem and there are some who have yet to speak with police. We know the incident was also witnessed by other passers-by and residents in the area and again, we would encourage anyone who saw anything or has any information to come forward. Please do not assume that we already have the important information that you hold.

"We are keeping an open mind about the motive for this incident. Please do the right thing and be assured we will treat all information in the strictest confidence."

The teenager's father, Hakim Galleze, said he has been "numb with pain" ever since the 17-year-old was killed. He added: "Every time my phone rings or there's knock at the door, I pray it is Nassem. Our beloved Nassem's life has been brutally ended and my family are devastated.

"People will have seen what happened and they will have heard things; you might be thinking do I talk to the police? Take a look at the car where my son died and you know there's only one thing to do for Nassem and our family. Please assist the police."
