Police search canal for missing Leicester man
Police and specialist divers are searching a canal as part of their investigation into the disappearance of a 67-year-old man.
Arthur Prosser was last seen when he left his home on Saxon Street, in Leicester, at about 1030 GMT on Friday 3 December.
Mr Prosser has Parkinson's disease, which can be affected by the cold, and does not have his medication with him.
Divers will search a stretch of the Grand Union Canal in Leicester.
Mr Prosser's son Graham launched a personal appeal for anyone with information nearly three weeks after his father disappeared.
Mr Prosser is described as white, approximately 5ft 9in (1.75 m) tall, with grey receding hair and of medium build.
He was wearing green trousers and a distinctive dark green jacket with a white tick on the back.
Leicestershire Police officers have been carrying out inquires around the local area and talking to the community to try to piece together Mr Prosser's movements.
