Searches are continuing in the Skegness area today for missing David Leman after reported sightings on Tuesday.
Police are also looking through the town and reviewing CCTV from the time of his disappearance on Monday morning, when he parked his car on South Parade to walk his dog Millie.
More than 200 people have also joined a Facebook event about a public search for David, after his disappearance prompted an outpouring of concern and support for his family, who are well known and liked in the local community.
A spokesperson for Lincolnshire Police said the decision on whether to approve the public search would be taken shortly, but warned there were problems associated with such a venture.
They said: “While it can be a big help, there’s an element of danger because we need to make sure the people searching are also kept safe - that’s why we don’t tend to put out public appeals straight away - but I’ve no doubt that’s something they are considering now.”
David, 51, is of mixed race, approximately six feet tall with a shaven head. His clothing has not been confirmed but is thought to be jeans and a hooded jacket.
Police searching for missing David had focussed their attention on Gibraltar Point on Tuesday afternoon and search teams and helicopters were spotted patrolling scrub land at the nature reserve.
Police received several witness reports identifying a man matching David’s description at the reserve yesterday, but nothing since.
Police would particularly like to hear from any dog walkers who may have seen David and Millie on Monday morning.
Millie is a black dog with a white patch on her chest and she was wearing a red collar.
The Coastguard helicopter and search teams have been searching for David and continued throughout Tuesday.
Rescue crews braved force eight winds and freezing temperatures to search the Skegness coast on Monday.
Coastguard crews from Chapel St Leonards, Skegness and Wrangle were joined by a Rescue 128 helicopter as they searched the dunes near Skegness and icy North Sea.
The 12 coastguards combed the beach between 9.50pm and 2am while the helicopter searched the sea but the only discovery was his dog and car on South Parade.
Chapel station manager Mark Smith said: “The weather was incredibly rough, we had force six westerly winds gusting force eight, snow showers and minus eight wind chill - it was tough conditions and a difficult search.”
Anyone with information which might help the police should call 101 immediately, quoting incident 451 of February 4.
