Wiltshire Police are appealing for information regarding the location of Christopher Savage, 39, from Chippenham.
Mr Savage was last seen on Saturday January 25 in Wilton Road, Salisbury. He requires medication and it is very out of character for him not to be in contact with his family.
He has links with Chippenham and Salisbury but may be anywhere in Wiltshire.
He is described as white, of very slim build and approximately 5ft 8ins tall. He has short sandy coloured hair and was last seen wearing grey jogging bottoms and a black coat.
Mr Savage's family and police are very concerned about his welfare and urge anyone with information to come forward. If you have information or have seen Mr Savage please call the Duty Sergeant at Salisbury Police Station on 101.
