A man who lashed out after seeing his partner embrace another man has been jailed for 20 months.
Dale Henry previously admitted an assault, which left four people injured, at the Great Wall in Lerwick in October.
Yesterday, the 37-year-old appeared at Lerwick Sheriff Court for sentence.
The court heard Henry had carried out the attack after seeing his partner embrace one of the individuals.
One man required stitches to a head wound and suffering “psychological harm”.
Defence solicitor Gregor Kelly said that Henry, who has a history of assaults, had turned over a new leaf but had reacted badly after drinking wine, to what he saw was a sexual advance on his partner.
But fiscal depute Duncan MacKenzie rejected this as an attempt to shift the blame to the victim.
Sheriff Ian Cruickshank said it had been “an inexcusable and frightening display of rage at a social event.”
He added: “As far as I am concerned it was totally unprovoked and has had a profound and lasting impact on the principal victim, who would have been more seriously injured without the intervention of the other complainants.”
He sentenced Henry, of HMP Grampian, to 20 months in jail to run concurrently with three other six-month sentences.
