A man has been jailed for attacking his girlfriend before setting fire to her house after getting drunk and taking laughing gas.
Hayden Parsons, 27, beat up his then-partner and torched the house she shares with her young children during a drink and drugs fuelled rampage.
Manchester Crown Court heard how Parsons had been out drinking with her at a pub in Manchester on the afternoon of Friday 13 March.
The couple had been together since November 19 and their relationship had developed very quickly, prosecutor Rachel Widdicombe told the court. They had been visiting the Vine pub in Manchester city centre together, where Parsons was known to the landlady.
The court heard that during the course of the afternoon, Parsons was seen by a member of staff sucking on a balloon - believed to contain nitrous oxide.
His behaviour quickly changed and Parsons left the pub, shouting at his partner to "get out now," the court heard.
"He grabbed her arm and pushed her out of the pub," Ms Widdicombe said.
"The defendant dragged her and pushed across the road with full force - she didn't want to go with him. He got her into a headlock and pulled her down to the floor. She was screaming."
The assault came to an end when a member of bar staff and another reveller intervened, causing Parsons to flee the scene.
Parsons then travelled to his girlfriend's house, which was empty, and broke in with a crowbar before setting fire to her bedroom.
"The defendant spotted a neighbour and asked if they had a crowbar as he needed to collect some of his belongings," Ms Widdicombe told the court.
"Mr Parsons managed to get into the house and a short time later the neighbour saw the defendant drive away. He then realised that the front door of the house was on fire."
The court heard how the woman's neighbour managed to get into her house and put out most of the blaze, before several fire crews arrived at the scene.
"There were four seats of fire in the house and the fire in the bedroom was still going when crews arrived," Ms Widdicombe said.
"A fire report stated that if the fire had not been put out quickly it could have developed and spread to other parts of the house."
Parsons handed himself into police five days later and said he had "done something" because he was "drunk."
Appearing via video link from prison, Parsons was jailed for three years after admitting one offence of common assault and arson being reckless to whether life was endangered.
Mitigating, his barrister Max Saffman said: "The defendant is a young man with difficulties involving the breakdown of relationships.
“His intention when he went to the house was to retrieve some of his property, I would suggest this was an impulsive action because he perceived he had been left by the victim.
“Although this was unpleasant for the victim, she suffered no injury from the incident.
“Mr Parsons tells me he is locked in his cell for 23 hours a day because of the ongoing situation and of course has not had any visits from his friends and family.”
Sentencing Parsons, Judge Hilary Manley QC said: “This was a low, mean and spiteful offence and was a very dangerous thing to do.
“Three fire engines attended and there were four seats of fire - there was a potential for a serious risk to life.
“Your cowardly behaviour was in contrast to the neighbour who risked his own safety to put out this fire.
“This was a revenge attack on the victim's home and you were under the influence of drink and drugs. Only a custodial sentence can apply."
