Police are appealing for witnesses after a teenager was punched in the face outside a Chinese restaurant in Royston High Street.

The 19-year-old victim was knocked out in the attack, which happened between 2.30am and 2.45am on Sunday, August 21, outside Rasa Sayangs.

When he regained consciousness, he walked back to his home before contacting police and going to hospital.

Det Con Dave Lawson said: “This incident happened when the town centre was busy with revellers getting food following their nights out.

“The victim himself was seeking something to eat after enjoying his evening, but instead he was the victim of an unprovoked attack and the impact caused him to lose three teeth.

“I’m sure that there will have been witnesses to this attack and I’m urging anyone who saw what happened or anyone with information to come forward.”

Anyone with information should call police on non-emergency number 101, quoting crime reference G4/16/677.
