Lerwick

A 17-year-old boy was also taken to hospital for treatment following the incident, which happened at about 16:00 on Tuesday at Gremista marina, Lerwick.

It is served by a ferry which runs between the island and Shetland, and there are also regular flights from Tingwall Airport, just outside Lerwick, to the island.

For the first time in the event's 143-year-old history, women and girls joined the main "squad" at the head of the torchlit procession through Lerwick.

The celebrations culminated in the burning of a replica Viking galley which lit up the Lerwick sky.

A yellow warning covering Shetland extended until 06:00 on Thursday, with Lerwick registering its strongest wind gust in seven years at 83mph.
