DETECTIVES are appealing for witnesses after a woman was indecently assaulted in Castle Gardens, Bishop's Stortford, at 1am last Tuesday.

Police say she was walking through the war memorial area when she was grabbed from behind by a man who told her he had a knife.

The man indecently assaulted her and ran off towards Castle Mound down Lime Tree Walk when a loud car horn startled him.

The man was white, about 6ft 1in tall, of medium build with dark, long, unwashed hair in an unkempt style. He had full lips, a large Adams apple, was unshaven and of pale complexion.

He was wearing a dark-coloured bomber-style jacket, loose combat-style trousers and a t-shirt with a white sports logo.

Anyone with any information should ring Detective Constable Karen Hussey in strict confidence on 01992 533458 or Crimestoppers on 0800 555 111.

Callers, who are given a unique reference code, do not have to give their name and may qualify for a cash reward.
