Thug boasted that he had just got out of jail

crying and becoming extremely aggressive – and he was escorted off the premises.

Judge Stuart Rafferty QC, who jailed Gill yesterday for ten years and nine months for incidents in Yorkshire and the manslaughter of frail Mr Robinson, said he left the pub with “self-righteous indignation booting the door”, damaging an inner panel.

Police officers Glenn Poole and Helen Balfour tried to restrain him but 39-year-old Gill was unco-operative, refusing to calm down and trying to break free.

PC Poole described both Gill’s eyes as being glazed and said he had a “wild expression” on his face, before he lashed out at PC Balfour, a foot shorter than him, striking her on her nose and damaging her glasses.

Gill broke free from PC Poole’s grip and hit him on his right cheek.

Gill ran away but PC Poole chased and restrained him. After Gill’s arrest and “no comment” answers to questions, he was bailed, going on to commit, “a catalogue of carnage”, said Judge Rafferty.

Course tutor Jamie Fisher recalled Gill arriving late on the day that Mr Robinson was fatally injured, appearing to brag to others he had just come out of prison for assaulting a policeman and his partner’s ex.

Mr Fisher described him as being animated and loud, constantly talking about violence and “bigging himself up”.

Gill attacked Mr Robinson on his half-hour lunchbreak. When he returned to the course, he continued to be disruptive and loud, and was asked to leave at about 2pm.

He left behind a soft drinks bottle, later analysed and found to have contained red liquid consisting of 22% ethanol.

“After the defendant was ejected from the course, it is clear from the evidence ultimately gathered, he embarked on a rampage of violence and aggression,” said Sarah Knight, prosecuting yesterday.

He shoplifted a bottle of vodka, Ribena and chocolate from Lidl in Ranson Road, then encountered a mother and daughter in their car.

They witnessed him throw a glass bottle out of the car window.

The mum told him not to throw rubbish as it harmed the enviroment.

Gill’s response was: “I know littering is wrong but so is arson and I’m more than happy to set fire to your car.” He then blocked their car.

The incident was witnessed by another driver who told the defendant he should let other people through as it was his own fault for throwing rubbish out of his car. Gill got out of his car and punched the driver to the head and face before driving off.

He filled up his car with fuel at a Doncaster service station at about 4.40pm, helped himself to some beer from the shop, and left without paying.

He went on to drive into the back of two cars, before he was stopped by South Yorkshire Police at 5.30pm. A breath test showed he was more than twice the legal limit to drive.

He hit two police officers after he was arrested and continued to be aggressive, even headbutting the van cage as he was transported to the police station.

His sentence for manslaughter was nine years, of which he will serve two thirds. A consecutive 12-month sentence was imposed for assault, causing bodily harm.

Then nine months was imposed on two assaulting emergency worker charges, relating to the Sheffield offences, consecutive to the overall sentence.

Concurrent sentences were imposed on remaining charges of causing criminal damage, theft, making off without payment and drink-driving. The headline sentence was ten years and nine months.

Gill was disqualified from driving for five years, starting from when he is released.
