Police have been combing gardens in Broughty Ferry as part of the search for a pensioner who has been missing for nearly a week.
Jack Greenway, 77, was last seen at the town’s Esplanade at around 11pm on Saturday evening.
The former Menzieshill High School geography teacher was wearing pyjamas at the time.
A large police presence has been in the town this week, with officers inspecting the Esplanade area for traces.
Officers could be seen searching gardens in Monifieth Road on Thursday.
Sniffer dogs and handlers have been at his home to detect his scent.
The coastguard and local lifeboat crews have also been involved in the search.
Mr Greenway’s family did not want to comment on the hunt.
Many of his former pupils have been sending good wishes for the popular former teacher on social media.
The keen environmentalist is a familiar figure in the community and was often seen picking up litter from the beach and parks.
Officers have already searched the Broughty Ferry Nature Reserve, Orchar Park, Barnhill Rock Garden and Reres Park, which are all close to his home.
Locals were urged to check sheds, garages and other outbuildings in case he has taken shelter from the cold and wet.
Mr Greenway is 5ft 8in and slim with white hair and a white beard.
A police spokesman said: “Mr Greenway is still missing at this time. Police inquiries are continuing to locate him.”
Sergeant Richard Grieve from Longhaugh Police Office thanked locals for everything they had done so far and urged them to keep looking.
“The local community in Broughty Ferry have been of great assistance to us in our efforts to trace Mr Greenway, with people checking their sheds and outbuildings, sharing our appeal, and also looking for him when they are out and about,” he said.
“While we are very appreciative of this, and we would ask everyone in the Broughty Ferry, Barnhill and Monifieth areas to keep an eye out for him, please ensure you stay safe when doing do.”
Anyone who thinks they have seen Mr Greenway since Saturday night or has any other information that could help in the search is asked to call the police on 101.
