Newly-released CCTV footage shows the chilling moments Sabrina Moss' killers stalked the streets before they gunned her down outside a grocery shop.

The killers were mostly members of the Kensal Green Boys (KGB) who were involved in a drug world turf war with the South Kilburn Gang also known as Family About Cash (FAC) or the Money Making Family (MMF).

The jury was told how the war – with weapons “designed to kill and maim at close quarters” - came to a terrifying climax in the early hours of the Bank Holiday in August last year as nursery teacher Ms Moss celebrated her 24th birthday.

Videos released by Scotland Yard today show how drug dealer Martell Warren, 23, was spotted driving his silver Vauxhall Corsa along Messina Avenue at about 2.25am and then again at 3am, with fellow gangster 29-year-old Simon Baptiste.

The pair, along with a woman, later visited a fast food shop and an off licence in Kilburn High Road. But Warren left Baptiste and the woman standing in the street when a group who had been travelling in a Ford Mondeo began walking towards them.

He then drove to Rondu Road where he collected his accomplices, Hassan Hussain and Yassin James, before heading back to Kilburn High Road.

At 3.55am, his car was seen slowing down outside a Woody's Grill takeaway where Ms Moss and her friends had gathered. He then drove it the wrong way down Messina Avenue before parking his car.

Two of the gunmen were then seen walking along Messina Avenue before hiding behind other cars so they had a clear view of the fast food restaurant.

Moments later they ran towards the takeaway, firing a Mac 10 and a shotgun. The bullets hit Ms Moss in her chest and arm, fatally wounding her. Her friend Sabrina Gachette, who survived, was hit in the back.

Warren, Hussain and James face life sentences for murder, while Baptiste is also expected to be jailed after being convicted of conspiracy to commit grievous bodily harm.

Speaking after they were convicted at the Old Bailey today, Detective Chief Inspector Andy Partridge said: "This was a callous act, committed by three individuals who were willing to fire a MAC 10 and a double barrelled shotgun indiscriminately at a group of people outside a busy restaurant.

"They waited until a large group of people were together and then fired at their victims.

"It is clear they wanted to injure, maim or even murder as many of those people as possible, without any consideration as to who was within that group.

"Both Sabrina Moss and Sabrina Gachette were the innocents caught up in something they had no knowledge of and no involvement in."
