A drunken 'bully' headbutted his girlfriend during a vicious attack at a teenage girl's birthday party before kicking off when police arrived.
Anthony Turner, 33, lashed out as his partner when she went outside to take pictures with her friends at the bash in Salford.
They were attending the celebration for a friend's daughter but the mood quickly sour as Turner became more and more intoxicated.
The party was eventually forced to relocate to a different house because of his bullying behaviour - but he followed them, Manchester Crown Court heard.
Once there he viciously bit his girlfriend's cheek and headbutted her in the nose, reports Manchester Evening News.
The police were called to the house in Irlam, and despite arriving with shields, Turner kicked out with ‘considerable force’ causing injury to one of the officer’s legs.
He pleaded guilty to common assault, assault occasioning actual bodily harm and assaulting an emergency worker and was jailed for 14 months on Thursday.

Prosecuting, Alison Mather told the court that on May 28 this year the couple held a party at their house for a friend’s daughter who had recently turned 18.
They had been together for about six months, but his partner described it as ‘not without its difficulties’ due to Turner’s ‘controlling behaviour’.
At one stage during the party he told her that he was ‘steaming’, she said.
“(His girlfriend) returned inside but it seems that he then started to become argumentative with other people in the property telling the guests to ‘get the f*** out of the house’," Ms Mather said.
“The young lady’s whose party it was became quite upset and left.
“His partner tried to calm him down but it seems he was still angry so a decision was made to move the party to the friends house nearby as her daughter whose party it was felt safer to go home.”
After returning to the friend's house, Turner then turned up and was initially calm, but after five or ten minutes, became argumentative again.
He was swearing and being abusive, saying: “I will slice your dog’s throat.”
Turner was grabbing his partner’s arm and twisting it back and then bit her on the cheek, which caused her to scream, the court heard.
As his partner moved to a different room he followed her.
“The defendant was shouting and trying to hug his partner and then she described that he headbutted her on the nose,” Ms Mather said.
“She felt like her nose was broken and it was bleeding.
“He then picked up a glass and started smashing it on his head".
Turner was then tasered, but he took the barbs out as it had ‘little effect’ on him, it was said.
His partner was left with swelling to her nose and a small mark to her cheek and the officer had bruising to his shin.
Turner was said to have previous convictions for domestic violence against a former partner in October last year.
These offences put him in breach of the suspended sentence he received.
In mitigation, Andrew Marsh said his client and his partner were still in a relationship.
“He is on sertraline and having talking therapy, he recognises he does have issues and is taking positive steps to address it,” he said.
Sentencing, Judge Alan Conrad QC told him: “I have no doubt you are a man who ordinarily is a decent man, but when you have had a drink you become a bully and you use violence towards women which is difficult to forgive.”
Turner, of Eldon Road, was jailed for 14 months and made subject of a restraining order banning him from contacting his partner for five years.
