A man had to be taken to hospital with a head injury after being assaulted by a group of teenagers in Margate.

The victim, in his 40s, was approached by the gang in the High Street and attacked.

Two 15-year-olds and a 16-year-old from Margate, and a 16-year-old Whitstable boy, have since been arrested on suspicion of assault and released while the investigation continues.

It is said to have happened between 7.30pm and 7.45pm on Thursday, February 8, but a witness appeal has now been launched.

PC Rob Hitchcock said: "Having followed up enquiries and CCTV opportunities, we would like to appeal for any witnesses to come forward who have not already spoken to an officer about it.

"In particular we are keen to trace a woman who came forward to help the victim, as she may have information which could help the investigation."

People with information are asked to call police on 01843 222289 quoting ZY/7205/18, or Crimestoppers anonymously, on 0800 555111.
