Attacked Dover teenager remains in critical condition
A 15-year-old boy remains in a critical condition in hospital with serious head injuries following an assault outside a newsagents shop in Kent.
The boy, who is in King's College Hospital in London, has undergone emergency brain surgery, police said.
Det Insp Jon Holl said he was attacked at about 21:45 BST on Saturday in Worthington Street, in Dover.
Officers are appealing for witnesses, in particular the drivers of two small silver cars.
Mr Holl said the cars were believed to have been a Peugeot 206 and a Volkswagen Polo, which were seen travelling through the scene at about the time of the incident.
He said the boy had been in Worthington Street with two teenage friends, one of whom had gone into the newsagents.
The teenager had been waiting on the street outside when "he had an altercation with another youth and some punches were thrown".
"I'm keeping an open mind as to what happened exactly after that, but the next thing is that he sustained really serious head injuries," he said.
Mr Holl added that there were about 10 people in the street at the time.
"This is not a young man who's part of a group going out to cause trouble," he said.
"This is a young man who's gone to the corner shop with two of his friends and then in the road outside been assaulted."
Officers have been using local authority CCTV as part of their inquiries, but have urged members of the public to come forward with any information.
"This could have been their 15-year-old son," Mr Holl said.
No arrests have been made.
