A 'violent bully' who viciously attacked his partner following a drunken row 'somehow got out of his handcuffs' while being taken away in a police van, a court heard.
Bartosz Mogila-Lisowski, 40, had been with the woman for three years, but theirs was a 'volatile' relationship which was exacerbated by drink.
She was at Mogila-Lisowski's flat in Salford in November last year, and the pair had both been drinking.
Mogila-Lisowski was texting his mother, which later caused a row with his partner after she had asked him to stop.
Her memory of what happened is unclear, prosecutors said, but Mogila-Lisowski admitted punching her to the face.
The police were called and overheard a 'heated discussion' between the couple.
When they knocked on the door, the woman answered and her face was swollen and bloodied.
Mogila-Lisowski was in the living room, and was arrested and taken away.
Her clothes had been torn, and she had to use towels to cover herself up, prosecutor Andrew Scott told Manchester Crown Court.
While in the police van, Mogila-Lisowski repeatedly banged on the cage and was behaving in a 'threatening and abusive' manner.
Mogila-Lisowski 'managed to somehow escape from the cage' and got into the main part of the vehicle.
There he 'lunged' at the two police officers.
They were able to stop the vehicle and restrain Mogila-Lisowski again.
The woman was taken to hospital and was found to have swelling and dried blood on her.
When he was interviewed by police, Mogila-Lisowski replied 'no comment' to questions.
He admitted two counts of common assault on an emergency worker, and changed his plea to guilty for an offence of assault occasioning actual bodily harm on the day of a proposed trial.
In May, while he was on bail awaiting sentence for these offences, Mogila-Lisowski, of Bridgewater Street, Salford, was fined by magistrates for spitting on a police officer's shoulder.
Now a judge has jailed Mogila-Lisowski for six months, after saying the offences were too serious for him to walk free from court.
Defending, Isobel Thomas had appealed for a suspended sentence to be imposed, saying Mogila-Lisowski has taken steps to tackle his heavy drinking.
Ms Thomas said Mogila-Lisowski would 'lose everything' if he went to jail, including his job as a shift supervisor.
Judge Alan Conrad QC told the defendant: "Over the course of an argument you launched into a vicious attack on your partner, causing significant injury to her face.
"She is a woman who is vulnerable, due to her emotional and other health problems.
"You are an intelligent man with a good work history, but it is clear you have a tendency to resort to violence when in drink.
"In drink you become a violent bully, as evidenced by what you did in this case.
"Your conduct here overall is so serious that only immediate custody can be justified."
