A serial domestic abuser who waterboarded one of his ex-partners is facing jail.

Jealous Sean Simmons, 28, from Hull, tied his then-partner to a bath before covering her face with a towel and pouring cold water over her from a bubble bath container.

Hull Crown Court heard Simmons, who once worked as a topless barman, then told her: 'This is what I do to people who lie. I'm going to make you tell the truth.'

Neil Jones, prosecuting, said the woman was 'struggling to breathe and thought in the heat of the moment she was going to die'.

Later the same day, on July 30, 2016, Simmons produced a white-handled knife 'and was telling her he would have to kill her'.

Mr Jones said: 'She really thought that the defendant would kill her. She seriously entertained that prospect on production of the knife.'

Judge Mark Bury adjourned sentencing for an assessment of the risk Simmons poses after hearing a total of six women have now suffered domestic abuse or violence at his hands.

Although the victim briefly resumed her intimacy with Simmons after both incidents, she has since moved the area to escape him, and said in a statement she 'would not feel safe if Sean is ever released from custody'.

She said: 'I'm aware how close to death I came in the short time I spent with Sean, and I do not believe I would survive if I came into contact with him again. I have to leave Hull. I believe he will kill some other female if he is not in custody.'

The couple met on Facebook that summer and 'almost immediately' began a sexual relationship, the court heard.

She was 'very fond of him' but gradually began to realise all was not well and he was extremely jealous. A month before the waterboarding, Simmons spat at the woman in bed while 'a couple of inches from her face', causing her to cry.

This had followed a 20-minute telephone conversation she had with her ex-partner, which became an 'obsession' of Simmons leading to the water torture.

Describing the waterboarding incident, Mr Jones said: 'It was initially, it seems, the proposal of the defendant that he would play a game with her - that he would actually tie the injured party to the bath and effect, in colloquial terms, waterboarding her.

'She was wearing a white T-shirt at the time and the defendant tied her wrists together with a dressing gown rope, and sufficient to make a discernible mark on her wrists.

Simmons (pictured), pleaded guilty to assault occasioning actual bodily harm, making a threat to kill, common assault, affray,assaulting a police constable, and two counts of sending malicious communications

'The waterboarding commenced by the application of a thick grey and white bath sheet placed over [her] face. She felt cold water being poured on her.'

By December last year, Simmons - who used to work as a 'topless barman' at the Duke of Cumberland in North Ferriby - had taken up with another woman who was to be the next victim of his jealous and controlling behaviour.

As well as sending her threatening messages, he gate-crashed a 'bath tub party' she was at armed with a knife, although the female householder 'courageously' also picked up a knife and ordered him to leave.

Simmons, pleaded guilty to assault occasioning actual bodily harm, making a threat to kill, common assault, affray,assaulting a police constable, and two counts of sending malicious communications.

He had spent 114 days on remand, his barrister Charlotte Baines said.

Simmons will be sentenced on September 14.
