Police in the north and north-east have joined forces with a national charity in an attempt to find a yachtsman who went missing around a month ago.
Antonin Mican, 32, from the Czech Republic, was last seen in Gardenstown, near Banff, on October 11 in his boat and was understood to have been heading to Wick.
No trace of him has been found since.
Officers have teamed up with the National Missing Persons Bureau and the Missing People charity to spread the appeal to a wider audience.
They will distribute posters featuring Mr Mican’s image as well as details about his yacht – the Swallow Tail.
Detective Inspector Norman Stevenson, of Aberdeenshire and Moray Division, said: “We have had a good response from members of the public so far, but as time goes on and Mr Mican is yet to be traced we are becoming increasingly anxious about his safety and the fact he may well have got into difficulty out at sea.
“We are working in partnership with the National Missing Person’s Bureau and the missing person’s charity, Missing People in a bid to glean new information about his whereabouts, but time is of the essence.
“We hope that these posters, which we will be distributing along the north-east coastline and further afield, will jog somebody’s memory if they have seen him.
“It appears that this boat is Mr Mican’s only form of transport and he could have stopped anywhere along the coastline. If anybody believes they have any information or may have seen him or the boat, I would urge them to get in touch with us and we can evaluate it on an individual basis, as it may be vital to the ongoing search.
“I would also appeal to Mr Mican himself to come forward if he is out on the seas or on land and sees the concern for him. I would urge him to call the police and let us know that he is safe and well so that we can inform his family.”
Anybody who has knowledge of Mr Mican’s whereabouts or who recognises his description is asked to contact the police on 101.
