Police have identified an "area of interest" in the search for two fisherman whose boat went missing off north Lewis in the Western Isles on Tuesday.

Douglas Craigie's body was found on Wednesday - the day before his 50th birthday.

But Norman Murray, who is 40 and known as Tam, and his 23-year-old crew-mate Murdo Morrison are still missing.

The Marine Accident Investigation Branch (MAIB) has put an exclusion zone in place for divers in an area between the Butt of Lewis and Port of Ness.

However, vessels can still operate in the area.

Specialist police officers are working with partners to search the zone for the missing men and vessel.

Police Scotland said it was believed the fishermen had sailed from Brevaig in Lewis at about 07:30 on Tuesday before travelling to the Port of Ness area to fish.

Their boat, the Kilda, was reported overdue at about 21:20 on Tuesday.

Extensive searches were conducted on Wednesday despite bad weather, with gale-force winds.

HM Coastguard stood down its operations on Thursday evening, pending any new information.

Police urged the local community not to put their safety at risk by carrying out searches in dangerous conditions.

Ch Insp Ross McCartney, local area commander for the Western Isles, said: "Our thoughts remain with everyone affected by this tragic incident.

"We are carrying out extensive work with our partners to further investigate the specific area in as safe a manner as possible.

"We understand how distressing and difficult this time will be for the families and we would ask that their privacy is respected."

Officers will remain in the Port of Ness area and anyone with concerns or information is urged to speak to them.

Ness is an area of rugged coastline, with many of its roughly 1,300 people living in crofting townships - small holdings where families can raise livestock and grow crops while working other jobs.

The parish has one of the highest concentrations of Gaelic speakers in the Western Isles.
