“Sadly he remains missing at this time. It is extremely unusual for him to have been out of contact with family and friends for this length of time and we remain very concerned for his welfare.
“I would urge anyone who believes they may have seen David at any time since the evening of Thursday, 9 December to get in touch.
“Anyone who may have dashcam or private CCTV footage from around the Broomielaw area or anything which may show David’s movements is asked to pass this on.
Anyone who has seen David, or who has any information on his whereabouts should contact officers through 101 quoting reference 1285 of 14 December.
David Fletcher is described as white, around 5ft 4ins in height with short grey hair. When he was last seen he was wearing a dark-coloured overcoat and flat cap.
