A YOUNG thug subjected workers in McDonald's and Tesco to a tirade of abuse.

The teenager also assaulted a police officer during a period of two months when he committed multiple offences.

Sheriff James MacDonald said the teen's behaviour was "deplorable" towards staff just going about their jobs.

The 16-year-old, from Rosyth, who cannot be named for legal reasons, appeared at Dunfermline Sheriff Court for sentencing.

He previously admitted that on August 10, at McDonald's, Fife Leisure Park, he behaved in a threatening or abusive manner which was likely to cause a reasonable person to suffer fear or alarm in that he acted in an aggressive manner, shouted, swore, refused to leave the locus when requested by staff members to do so, activated a fire alarm, challenged staff members to fight and spat.

He also previously admitted that on August 12, at Tesco, Turnstone Road, he assaulted an employee and knocked him to the ground to his injury.

And, on October 15, in Rosyth, he assaulted a police officer by butting him on the head.

The court heard that the teen had gone to McDonald's at 9.30pm appearing under the influence of alcohol and to be volatile.

As he was shouting, swearing and arguing with a female companion, staff asked him to leave.

"But he simply ignored the member of staff," depute fiscal Dev Kapadia said.

The teen was asked to leave again by a different member of staff but started shouting and swearing.

One female employee tried to usher the boy out and as he left he pressed the fire alarm, setting it off.

The teen returned to McDonald's this time trying to fight a female worker and asked to fight any male members of staff.

He then spat on the floor next to the employee and picked up a fire extinguisher and attempted to take it outside.

Staff managed to flag down police on patrol and they found the accused running out of the leisure park.

Two days later at Tesco, a security guard found the teen in the toilets and asked him to leave, the court heard.

Mr Kapadia said the teen accused the employee of "touching him".

The security guard denied this and immediately tried to leave but the accused blocked his exit.

At around 9pm, he was standing by the CCTV monitor when the teen returned to say: "Are you going to touch me up?"

The complainer tried to ring for help but the teen prevented him and then ran out of the store.

The boy also walked up to the member of staff and put his foot around his ankle causing him to fall and strike his head, leaving the complainer with minor injuries.

The teen assaulted a police officer when he called the emergency services to say he was going to harm himself, the court heard.

Officers found the accused at home where he started acting in an aggressive manner and headbutted one constable to the face.

Defence solicitor Alexander Flett said: "I think this is indicative of immaturity.

"He has started a construction course and it seems in that time there has been an increase in maturity."

Sheriff James MacDonald said: "If you were of age, without hesitation I would have sent you to prison for these offences.

He imposed 160 hours of unpaid work, a restriction of liberty order for two months and 18 months of supervision.
