Police are seeking a second man in connection with a car crash that killed three teenage pedestrians in west London on Friday night.
A 28-year-old man has been arrested on suspicion of dangerous driving after a black Audi, believed to be travelling at speed, mounted the pavement on Shepiston Lane, Hayes.
It is understood the three victims, named locally only as George Wilkinson, Harry Rice and Josh Kennedy, had been on their way to a birthday party at a nearby football club with friends when they were killed.
Now the Metropolitan Police have said they believe at least one other male travelling in the Audi fled the scene.
“At least two males are reported to have left this car following the collision,” a police spokesperson said.
“Enquiries are ongoing to establish the full circumstances of the collision and the number of occupants in the vehicle involved.”
Despite the efforts of paramedics, all three were pronounced dead at the scene.
The victims are all believed to be teenage males, aged approximately 16, although police said they were awaiting further information.
The boys’ next-of-kin have been informed, although formal identification is yet to take place.
A 28-year-old male who was inside the vehicle was arrested and then taken to a west London hospital for treatment. He will be taken into custody once he is discharged.
The suspect was being questioned at a north London police station on Saturday night.
Police have said the incident is not being treated as terror-related..
One tribute left at the scene read: “George Boy, I love you so much, love Kev, Vinnie.”
Another said: “I thought I would never have to write this and I don’t know what to write but I will always love and miss you millions.”
Elsewhere, a card read “To my bro, always together forever,” while a fourth said: “To my darling baby boi my heart is broken, love mum, Vinnie.”
Detective Jane Shaw, of the Serious Collision Investigation Unit, said: “These are horrific circumstances that have resulted in three young people on a night out losing their lives.
“Dedicated family liaison officers have been put in place to support the next-of-kin of the victims. Our thoughts are with them.
“We know that there was a large party nearby and many people would have been travelling through the area and saw what happened or witnessed the aftermath. I need these witnesses to contact police immediately.
“We are also particularly keen to trace other motorists travelling through the area at the time.”
