A 14-year-old Austrian student was left with a broken jaw and facial injuries after he was approached by three youths.

The assault happened in Pierremont Park in Broadstairs High Street as the victim and two other Austrian boys were sitting in the swing park.

Police say the three youths began swearing and shoutng at them. One of the thugs said to the victim: "Have you heard of David, the king of Broadstairs?"

The ringleader then punched the victim in the head and demanded money. His accomplices set about a second foreign student at which point the third Austrian tried to intervene and he was then confronted by all three attackers.

Two of the students ran away while the third was attacked further by the three youths and kicked while on the ground. He managed to pick himself up and punch his attackers before running off.

The attackers are all thought to be aged between 16 and 17. One was 5ft 6in tall, slim, with short dark brown spiky hair. He wore white or grey tracksuit bottoms, a red top with writing across it and trainers. He also wore a silver chain. Another attacker was pushing a bike.

Police have issued an electronic likeness of one of the attackers. Anyone who knows the identity of any of the boys, or who witnessed the incident on August 28, at about 9.15pm is asked to contact Det Con Katrina Whitehead at Margate Police Station on 01843 222 151.
