HM Coastguard confirmed it was assisting Police Scotland, but referred all queries back to police.
Clackson is the Orkney Islands Council member for the North Isles Ward, which includes Papa Stronsay.
Clackson, who lived on Sanday – an island just north of Stronsay, told RNZ he had not yet heard any local discussion of the case or seen any police activity.
However, he was invited to visit the monastery in March last year.
“We enjoyed a tour of the island and of the monastery and were made to feel most welcome. It is impressive everything that The Sons have achieved in the quarter-century their order has been present on the island, and all that they currently do and have planned for the future,” Clackson wrote in his regular newsletter to constituents, noting he was familiar with many aspects of their daily lives, having lived in Iona, another community with an orthodox monastery.
He told RNZ the Papa Stronsay monastery was in his council ward and the monks were among his ward constituents.
“I know several of them personally [although I know them by their monastic names, rather than their birth names], and I have visited the monastery,” he said.
“They are often seen on the ferry travelling back and forth to Kirkwall [Orkney’s capital], eg to do shopping in the supermarkets or en route to travel further afield. They have a house and chapel on Stronsay in the village of Whitehall and engage with the community there.”
While the island was small, it was not entirely isolated, he said.
“Papa Stronsay is just off the island of Stronsay, and the monks have a small boat which connects them with the village and port of Whitehall on Stronsay, just on the other side. From Whitehall, there is a ferry service to Orkney’s capital, Kirkwall [and sometimes to other neighbouring islands]. There is also an air service from Stronsay to Kirkwall.”
Clackson said he hoped Evans was “found safe and well soon”. He did not respond to RNZ’s queries about whether Evans was one of the monks he had met during his visit to the monastery.
