Shoppers, motorists and church-goers are among those being targeted by police as they continue their hunt for a 90-year-old man reported missing a week ago.

William Ritchie, known as Bill, was last seen in the West Road area of Fraserburgh, Aberdeenshire, at around noon on January 12.

He was reported missing two days later, sparking a major operation to find him.

Despite CCTV checks and searches around the town involving specialist officers, no trace of him has been found.

On Sunday, officers are to hand out leaflets and stop drivers in the hope they can jog people's memories to remember information that could help.

Officers will be speaking to motorists at Boothby Road, a street Mr Ritchie regularly walks, in case anyone remembers seeing him, and they will be handing out posters at local shops, licensed premises and churches.

Inspector Kevin Goldie said: "It has been one week since Bill was reported missing and there has been no trace of him since despite a major search taking place in the town to track every route he's been known to walk in the past.

"Despite being relatively fit and healthy for his age - as far as we know - we are now seven days on and what with the weather we've had to contend with and the lack of contact, our concerns for him grow every day.

"People continue to come forward with information and we continue to be extremely grateful for this help. I know the local community is anxious to know where Bill is, and I can provide every assurance we are doing everything we can to find him."

Mr Ritchie is described as being around 5ft 7ins, with a slim build and short grey hair. He usually wears a black jacket or a waterproof jacket with the hood up, and a flat cap.

He regularly visits Asda, the local Co-op and the post office on Mid Street.

Anyone with information should is asked to contact police on 101.
