Three people were towed to safety after the engine on their leisure boat caught fire off West Burra.
The Shetland Coastguard helicopter, Lerwick and West Burra coastguard rescue teams, and the Aith lifeboat were called into action at about 12.30pm this afternoon after a call stating the engine of the vessel was alight and the 20 ft boat was drifting.
When the helicopter arrived the vessel was found to be in no immediate danger.
Nearby boats towed the boat into Hamnavoe where they were met by coastguard rescue teams. Nobody was hurt in the incident.
