A search is underway for a ferry worker who has been missing from the boat overnight.

Alistair Gibson, known as Charlie, was reported missing from the MV Hjaltland late on Wednesday.

The 58-year-old crew member from Orkney was last seen at around 9.10pm.

The ferry he was working on left Aberdeen bound for Lerwick at 7pm.

He is described as around 5'7'' in height with short balding dark hair and is of slim build with slight facial stubble.

When last seen he was wearing a navy blue uniform with the NorthLink Ferries logo and glasses.

A search of the boat was carried out overnight and the Coastguard also assisted with searches.

Shetland Area Commander Chief Inspector Lindsay Tulloch said: "We are continuing our enquiries to trace Charlie and would urge anyone who may have information to contact us.

"We have spoken to passengers who were on board the ferry today and have continued with searches today.

"If Charlie is reading this, we would urge him to get in touch to let us know that he is safe and well."

Anyone with information is asked to contact Police Scotland on 101.
