A teen has suffered “life-changing” injuries including a fractured skull after being assaulted by three men, one of whom used a hammer.

CCTV footage has been released of three men police have linked to an assault which took place last August in Oaklands Passage, Brent.

The 19-year-old was taken to hospital and treated for his injuries following the attack, which has left him continuing to have seizures as a result.

Footage showed three suspects enter an alley in Oaklands Passage around 5.20pm on August 2 2016 and run off towards Cricklewood Broadway shortly after.

It is believe one of the attackers punched the victim in the face then the other two pushed and kicked him to the floor.

One of them was said to have used a hammer while another used a glass bottle, leaving him pleading on the floor.

Detective Constable Rupy Ghatrora said: “This is a shocking incident which has left the victim with life changing injuries.

“We are keen to identify the three men in the CCTV footage so we can speak to them about the incident.

“We would also urge anyone who witnessed the incident to contact us."

One suspect is described as an Asian man wearing a black jacket, black tracksuit trousers with ‘Adidas’ written down the side and black trainers with white soles.

He was carrying a blue ‘man bag’.

Another is described as an Asian man wearing a grey tracksuit and trainers.

The third is described as a tall Asian man wearing a black jacket, grey tracksuit trousers with a white stripe down the side and black trainers.
