A 25-year-old woman stripped off some of her clothes and offered an elderly man sexual services before assaulting him.

Louise McDougall, of Mount Avenue, Montrose, was found guilty of assault by a jury at Dundee Sheriff Court, and she was found guilty of behaving in a threatening or abusive manner and attempting to pervert the course of justice.

The incident happened on December 29, 2013, at the victim’s home in Montrose.

A jury found McDougall guilty of behaving in a threatening or abusive manner by shouting, swearing and demanding money from the 87-year-old, placing him in a state of fear and alarm.

She was also found guilty of locking the front door of the man’s home, removing some of her clothing, offering the provision of sexual services, stamping on his leg, repeatedly demanding money from him, and repeatedly striking him on the head and back with a fireside implement, to his severe injury and permanent disfigurement.

And she was found guilty of a charge of attempting to pervert the course of justice by phoning 999 and making a false allegation that she had been raped and sexually assaulted by the victim.

Following the verdict fiscal depute Eilidh Robertson presented a schedule of McDougall’s previous convictions including assault.

Defence advocate Jonathan Crowe, QC, said: “Your ladyship has heard of some difficulties McDougall has had in her life – drug difficulties, which are now behind her.

“But there may be other difficulties which your ladyship would like to know of which would become apparent in a report and therefore I would like to save mitigation for when that is available.”

Sheriff Elizabeth Munro deferred sentence until February 25 for reports.

Addressing McDougall, she said: “These are serious charges made worse by your previous convictions.

“If you weren’t pregnant I’d be remanding you in custody just now.”
