A 15-YEAR-OLD boy was headbutted for no reason by a drunk man in Rosyth.

The attacker, John Duncan, then pursued a woman who had been walking her dog nearby.

He tried to get into her home then smashed glass in her front door.

The shocking incident led to Duncan, 33, of Meadowfield, Dalgety Bay, being sentenced at Dunfermline Sheriff Court.

He admitted that on November 3 last year at Heath Road, Rosyth he assaulted a boy then aged 15 by seizing him by his clothing and headbutting him, causing him to fall to the ground to his injury.

He also admitted that in Heath Road and Ramsay Place he shouted, swore, pursued a woman, repeatedly banged on her door then threw a bin at the door, smashing a pane of glass.

Depute fiscal Dev Kapadia said at 8.40pm the 15-year-old boy had just finished working at a local take-away when he saw Duncan who was “under the influence of alcohol and singing songs”.

The two were not known to each other but Duncan launched an unprovoked attack, grabbing the boy then headbutting him.

A woman was walking her dog nearby when she heard shouting and the boy ran towards her telling her what had happened.

She told him to go home and Duncan then came towards her, apparently following the boy.

He then turned his attention to the woman because her dog was barking at him.

The woman headed home and was pursued by Duncan. When she got into her house, she heard him trying the door but she had locked it.

He then began banging on the door then threw a wheelie bin at it, smashing the glass.

Defence solicitor James Moncrieff said: “He has very little memory of the incident but it’s clearly not a very pleasant offence.”

Sheriff James MacDonald told Duncan: “These are concerning offences. Violence against a child which was entirely unprovoked and then you follow this lady home.”

He pointed out that Duncan has “a history of violent offending”.

The sheriff imposed a community payback order with 12 months supervision and 180 hours of unpaid work.
