When Craig Doherty was asked to leave a nightspot at the weekend he became abusive towards door-staff.
But things got worse for the 34 year-old from Glasgow when he continued his aggression after his arrest. His behaviour climaxed with a head-butt against a cell door – which hurt nobody but himself.
Appearing from custody at Lerwick Sheriff Court, Doherty – of the city’s Chirnside Road – admitted behaving in a threatening or abusive manner at Da Wheel, and aiming threatening comments towards door staff.
He also admitted throwing a cup of tea after being taken into custody, and head butting the door in question.
Doherty carried out the offence on Sunday while he was on bail.
Defence agent Tommy Allan said Doherty had been working as a concrete finisher, but expected to lose his job as a result of his behaviour. His continued presence in the isles was, he said, unlikely as a result.
“It’s more than likely he’ll be on the boat at seven o’clock today. He has no particular reason to return to Shetland.”
He said Doherty did not usually drink, but had been “drinking all sorts of spirits” on the night in question.
Mr Allan said the threats that Doherty made were “completely without substance” and amounted to “drunken nonsense”.
Doherty wanted to apologise for his behaviour, said Mr Allan.
Honorary sheriff Arnold Duncan fined Doherty £400 for the offence.
