Detectives believe a King's Lynn man missing for more than a month could now be in the Sheringham area.

Darren Siggins was last seen at his North Lynn home on December 22 and a fresh appeal for information has been made as police grow increasingly concerned for his safety.

The vulnerable 39-year-old spoke to his family briefly by telephone on December 27 when he was said to have been feeling very low.

Officers visiting his home found his mobile phone and the medication he must take every two weeks.

Information received by the police suggests he could have travelled to the Sheringham area and posters are being distributed across north Norfolk.

Mr Siggins is 5ft 8ins and slim, with short mousy-brown hair. When last seen he was wearing a short dark jacket, white trainers and either tracksuit bottoms or jeans.

Anyone with information is asked to contact police on 101.
