Sick sadist filmed as he raped partner

had a bad record for violence, including several jail terms.

Oliver smirked as he was led handcuffed to the cells. He will be sentenced in December.

The rape victim told how she initially felt sorry for Oliver when they started dating in 2017.

She held down a good job as a support worker while he was unemployed.

But she said he “basically moved in without my consent”.

Jurors heard he made a Google search for “most violent brutal torture porn”.

She soon suffered at his bullying hands and he became obsessive, demanding to know where she was.

The woman told jurors: “It felt like he was just taking over my life. I felt like I was walking on eggshells.

“I did not want to come home from work as I did not know what mood he would be in.”

In June last year the woman had to beg Oliver to let her meet a friend.

He only agreed if she went to the same pub as him and wore a cardigan to cover bruises he caused.

They later returned to the mum’s home, where the thug flew into a jealous rage.

The woman recalled: “He put me in a headlock. I thought he was going to snap my neck.”

She eventually passed out and when she woke Oliver grabbed her face so hard he dislocated her jaw.

The victim managed to escape and dialled 999 at a nearby phone box.

Despite what happened, the woman was back in contact with Oliver in October 2018.

The pair went out in Glasgow before returning to her home.

When the woman refused to have a gin with Oliver he put her through a horrific ordeal.

The sobbing victim recalled: “He was on top of me and he stripped me. I was telling him to stop.

“He was saying: ‘ I am going to teach you a lesson. You are my property’. He said he was going to torture me.”

Prosecutor Bill McVicar asked the witness: “How long did this go on for?”

She replied: “Hours.” The terrified woman was physically assaulted, raped and tied up.

She told Mr McVicar: “He repeated all the things that he did in each room of the house. I just thought that I was going to die.”

Oliver also dragged the screaming victim into the bath.

She said: “He was pushing my face in the water, in and out. He was trying to drown me.”

The woman was dumped in a cupboard for being “disobedient”.

Oliver filmed what he was doing and clips were played during the trial.

Detective Sergeant Claire Jack was one of the officers who later viewed the footage

Defence counsel Iain McSporran asked her: “Have you ever seen anything quite like that?”

She replied: “Not in relation to another adult, no.”

The court heard the victim managed to sneak out after Oliver fell asleep.

But even after he was held on remand he continued to contact her.

He was convicted of causing the victim fear and alarm with the prison letters and phone calls.

She told him: “I am petrified of you. I don’t want to see you again. Leave me alone.”

He had earlier sexually assaulted another woman at his then home in September 2017.

Lord Armstrong ordered a full risk assessment should be carried out on Oliver.

This could eventually lead to an order for lifelong restriction being imposed.
