The coastguard helicopter has joined the search for a German tourist missing in the Western Isles since Friday.

The Hebridean Mountain Rescue team and Maritime and Coastguard Agency have also joined the search for Torsten Kulke, who has been reported missing from his home in Germany.

The 48-year-old was last seen near Aird Uig in Lewis at about 6pm on Friday and was reported missing on Monday.

Search activity took place on Tuesday in the area where Mr Kulke was most recently seen.

The search and rescue coastguard helicopter from Stornoway has been providing air support.

When last seen Mr Kulke was wearing a white top, khaki trousers, heavy walking boots and carrying a rucksack.

He is 6ft 3in, of medium build with light brown hair.

Inspector Jane Nicolson said: "We are increasingly concerned about Torsten's safety and well-being and I must urge anyone with information about his whereabouts to get in touch as soon as possible.

"Torsten may have travelled further afield on Lewis, and while searches so far have focused on the Aird Uig area I would urge people elsewhere on the island to get in touch if they believe they have information which could assist."

Anyone with information has been asked to make contact with Police as soon as they can by calling 101, quoting reference NH 2952/17.
