A rapist blackmailed a woman into sex after she found he had intimate photos of her on his phone.

Kevin Adair, 34, attacked the victim at a flat in Greenock, Inverclyde days before Christmas in 2014.

The incident came during a seven-year campaign of terror against a total of five women.

Adair was found guilty at the High Court in Glasgow on Monday.

The trial heard how the victim was blackmailed, and Judge Michael O'Grady QC said he preyed on the women "like a cat with a mouse".

In his speech to jurors, prosecutor Duncan McPhie said: "She understood that he had photographs of her - compromising photos.

"She told you that she had sex with Adair only in return for him deleting them from his phone.

"You might think he had a hold over her because of these photographs."

The court heard Adair described as "very charming", but also "very controlling".

He had earlier sexually assaulted a then lover at a house in Dumbarton, West Dunbartonshire in 2007.

Adair would call her names and checked her intimately to make sure she was not cheating on him.

He also kicked and headbutted another woman because she mentioned higher exams he had once sat.

The abuser hounded a further victim, bombarding her with texts asking where she was, and then pushed her, causing her to fall down stairs at a flat in Helensburgh, Argyll and Bute in 2011.

The court heard another woman was punched as she clutched a baby.

She recalled how she "cried five days out of seven" every week during their relationship.

The jury heard the scared woman lied to the police and a midwife to cover up her ordeal.

Adair was convicted of seven charges including rape and a number of assaults.

Judge O'Grady said it appeared Adair took "sadistic pleasure" in carrying out the crimes some against women who had looked to him for "protection and care".

Adair will be sentenced on July 25 in Edinburgh.
