A teenager has been sentenced to 14 months in a young offenders institution after creating chaos at a hospital and obstructing emergency workers.

Sally MacLennan of South Lochs, Lewis, was told her actions delayed a child's treatment at the Western Isles Hospital's A&E department.

Procurator fiscal Karen Smith said MacLennan was taken to the hospital on the evening of December 23 and ended up lying on the floor outside the treatment room being generally disruptive, shouting and swearing, and refusing to cooperate.

The 18-year-old was flailing and thrashing her arms and legs out on the floor when police arrived, while other people including children were waiting, said Ms Smith.

Because of the disturbance she caused, one father went home with his child and had to return to the accident and emergency department later.

In a separate incident, Maclennan spat on a paramedic and a police officer and obstructed staff at the same Stornoway hospital.

Sheriff David Sutherland said MacLennan's "appalling behaviour" meant he had no option but to hand her a custodial sentence.

Lawyer Angus Macdonald said his client was due to start a cookery college course and "potentially has a good career in front of her" but alcohol was a "poison" to her.
