POLICE launched an appeal this morning (Tuesday) for witnesses and information following an assault at the weekend.

It took place on Market Place in Hitchin at around 2am on Saturday.

A group of two men and two women, who had just left a night club on the square, were approached by a group of three men.

One asked for a lighter and a verbal altercation followed. The three men are believed to have then assaulted the two men and one of the women.

The first man is described as white, with dark hair, wearing a white T-shirt and a black biker-style leather jacket.

The second was white, with dark hair, wearing a yellow polo shirt.

The third is described as white, 6ft tall, with a shaved head which had designs cut around his temples. He was wearing a dusky pink polo shirt.

Dc Nigel Humphrey, who is investigating, said: "This incident took place in the early hours of Saturday morning when people were coming out of local night clubs so someone must have seen it take place.

"If you believe you witnessed this incident I would strongly urge you call me via the non-emergency number 0845 33 00 222 citing crime reference number G1/09/888 as soon as possible. Alternatively you can call Crimestoppers anonymously on 0800 555 111."

An 18-year-old and a 16-year-old from Edmonton were arrested in connection with the incident and released on police bail until June 3.
