A 'Jeykll and Hyde' woman beater's sinister past involves battering pregnant girlfriends and spitting at his own nan.
Mark Doyle was jailed for making a young mum's life "a living nightmare" with a truly disgusting "campaign of terror".
The 35-year-old targeted an "extremely vulnerable" victim, who he humiliated and degraded "on an almost daily basis".
He mocked her weight, put her food in a dog bowl, wouldn't even let her go to the toilet alone, and destroyed her clothes.
Doyle stabbed, punched, bit and choked the woman, robbed her at knifepoint, and disgracefully also wished her children dead.
The vile bully, of Frederick Street, St Helens, already had a history of attacking women, including three former partners.
He has 17 past convictions for 25 offences and the ECHO can now reveal the details of his past crimes against women.
In 2011, Doyle was convicted over an attack after he accused his then girlfriend of seeing other men while he was in prison.
The jealous yob punched her to the face, grabbed a knife and threatened to stab her, but she managed to escape the house.
Jamie Baxter, prosecuting, told Liverpool Crown Court: "He dragged her back in and continued to beat her."
Doyle was handed a six-month jail sentence, suspended for 12 months, which was later activated for a breach of the order.
In May 2012, Doyle was convicted of battering his then pregnant girlfriend, after he sunk his teeth into her during a row.
Mr Baxter said: "He punched her to the face, she was scared and called police, and he bit her during the incident as well."
He said because the victim was pregnant she couldn't undergo an X-ray, but it was suspected he may have broken her arm.
Doyle, who was convicted of assault causing actual bodily harm and breaching a restraining order, was locked up for 14 months.
In December 2013, he was locked up for five months and given an indefinite restraining order for attacking another pregnant partner.
Mr Baxter said: "He punched and kicked her, and strangled her, doing so while she was pregnant.
"She describes the ongoing impact of his abuse, which echoes his partner in this case."
In September 2016, he was convicted of common assault against a third previous partner, when he was jailed for 12 weeks.
Mr Baxter said he and the woman had argued when out drinking, which led to Doyle headbutting her, and she fled in terror.
The prosecutor said: "He chased her and spat at her, and punched her to the face and body."
In December 2016, Doyle was convicted of battery and harassment, plus breaching a restraining order made to protect the victim.
Mr Baxter said: "He had an argument with his then partner, at the address they shared with the defendant's grandmother.
"He left, returned later and assaulted his grandmother, by pushing her.
"He was making efforts to get to his ex-partner, but the grandmother tried to stop him. The defendant also spat in her face."
He admitted battery and harassment, but was handed two months in jail, suspended for 18 months.
Doyle, a drug addict and alcoholic, started abusing his latest victim in February 2019 and it continued over a 13-month period.
Mr Baxter said: "He began to regularly abuse her by throwing empty cans of lager at her, cut up her clothes or poured bleach on them, or poured shower gel all over her, as part of his perceived complaint about her hygiene.
"In her words, it made her feel utterly degraded."
Doyle admitted controlling and coercive behaviour, robbery, two counts of battery, criminal damage, assault causing actual bodily harm, and malicious communication.
He was likened by his lawyer to "Jekyll and Hyde", the split personality character from the Robert Louis Stevenson novel, Strange Case of Dr Jekyll and Mr Hyde.
Desmond Lennon, defending, said: "When he's not affected by alcohol or drugs he behaves reasonably and in a controlled way."
Judge Garret Byrne said Doyle's conduct towards the vulnerable victim was "truly appalling" and he was "dangerous".
He said: "This is one of the most serious cases of its type that the court has seen in recent years."
This means he must serve at least two thirds - five years - behind bars, before he can apply for parole.
