The son of a missing man who suffers from Parkinson's disease said life has felt like a "bad dream" ever since his father's disappearance.
The family of Arthur Prosser hope they will soon know more about the 67-year-old who disappeared three weeks ago today.
Mr Prosser went missing from the Narborough Road area of Leicester at about 10.30am on December 3, and has not been seen since.
He does not have any medication with him and failed to pick up his prescription from a pharmacy in Leicester, police said.
His son Graham said the last few weeks without his father had been a nightmare. "It's been three weeks now and I just want him home," he said.
Mr Prosser is white, approximately 5ft 9in, with grey receding hair that has some dark specks.
He is of medium build, walks with a limp and holds his left arm up against his waist. He was wearing a dark green jacket with a white tick on the back
