Today, it has come to light that Paul Doyle, a man involved in the notorious Liverpool parade attack, once aggressively confronted a colleague during a work-related go-karting event. This incident reportedly led to his dismissal from his job.

The 54-year-old was terminated from his position after his behavior was described as ‘psychopathic’ by colleagues, following aggressive actions towards fellow employees.

According to an anonymous source from the large engineering company where Doyle was employed, he lost his IT job due to ‘intimidating’ conduct towards his line manager.

During a workplace go-karting outing, Doyle, who is known for his muscular build, allegedly pulled a colleague out of a kart, pinned him against a wall, and shouted at him for overtaking him on the track.

In a separate incident, while driving colleagues to Milan Airport during a business trip to Italy, Doyle reportedly grew impatient with traffic and bypassed the queue by driving in a closed lane.

These accounts, dating back to the 2000s, were shared by a former colleague of Doyle, an ex-Royal Marine. The source expressed shock at Doyle’s involvement in the road rage incident against football fans last May but admitted that his participation was not entirely surprising.

The colleague said that while he had a good relationship with Doyle – because they were on separate teams at the same level so there was ‘no friction’ – he was a ‘loose cannon’.

Doyle was jailed for 21 and a half years on Tuesday after he admitted dangerous driving, affray and 29 other GBH-related charges in connection with the mowing down of more than 130 Liverpool FC fans who were celebrating their club’s title-winning season.

Liverpool Crown Court heard that – although Doyle was thrown out of the Marines for fighting and served 12 months imprisonment 30 years ago for biting the ear off a sailor during a drunken fight –  he had turned his life around on his release.

But the revelations from the ex-colleague, who asked not to be named, cast doubt on claims he kept out of trouble for the following three decades.

The worker was employed with ‘Doyley’ at a large multinational engineering company in north west England between 2006 and 2008, when he was fired.

The married father-of-one said: ‘Paul joined around 2006/7 and was a network engineer. If we opened a new office, he would go and set up the network equipment. I was on the next desk and would see him pretty much every day.

‘When I first met him, he was one of the friendliest people you could meet, very happy-go-lucky.

‘I never had any issues with him. He was like the naughty kid at school, hyperactive. I always used to ask, how does your missus put up with you?’

‘He would throw things across the office and wind people up. There was always banter and for him to say he didn’t like football is bullshit.

‘He was an Evertonian and I’m a City fan – neither team were doing that well back then and we’d talk about it all the time.

‘He knew his players and he did fantasy league. He’s well-built and was very fit. I know he used to get up running at 5am and had massive arms. I joked about whether he was on steroids.

‘He’d say “I wouldn’t touch that crap”.’

But the ex-colleague revealed: ‘Then there was this other side.’

Recounting the go-karting incident, which happened ‘not long before he was sacked’, he said: ‘Doyle was racing around and I think one of the guys cut him up or something. 

‘Paul stopped his car in the middle of the track, got out and pulled the other guy out of his go-kart and pinned him up against the wall. He grabbed him by the throat and started screaming in his face.

‘It shows you how strong the guy (Doyle) is to pull a grown man out of his car. It lasted a couple of minutes – people came over to break it up and the workers from the track were like ‘what’s going on here’ and he was pulled away.’

The Mail tracked down the other go-kart driver, who did not want to be named but who confirmed the incident took place.

He said: ‘Everyone now knows what kind of person Paul Doyle is.

‘He’s got anger problems. He’s one of those people who, if he gets angry with you, he doesn’t say anything, he just attacks you.

‘He nearly lost his job over it but didn’t because I didn’t really pursue it.

‘I think it was his first and last warning.

‘It is a mental problem – he can’t control his anger, which is what happened in Liverpool.’

Soon afterwards, it is understood there were complaints about Doyle, a married father-of-three, being ‘aggressive’ to his manager – who described him as a ‘psychopath’.

The ex-colleague said he was not sure whether it was a combination of both incidents or just the complaints from the former manager which led to Doyle losing his job.

He claimed Doyle’s team did not take the Italian motorway incident – which happened a year earlier in 2007 – too seriously as nobody was hurt.

But the ex-colleague recalled telling him, ‘you are f****** crazy, you are going to get arrested’ and he just replied, ‘it’s alright’.

‘We just thought of it as banter, as a joke, almost,’ the ex-colleague added.

Chillingly, similar disregard for the rules of the road was demonstrated by Doyle in the minutes before the Liverpool attack, with him driving recklessly, undertaking cars and jumping a red light.

The ex-colleague said Doyle’s conduct, revealed in distressing dashcam footage, which showed him shouting and swearing at pedestrians as he mowed them down, was ‘the kind of behaviour I expected from Paul’.

He said that, when Doyle was escorted from the premises after being dismissed, he began ‘yelling, swearing, getting really aggressive, shouting, “you’ve f****** nothing on me” and “I’ve done nothing”.’

‘I certainly understand why people felt intimidated,’ the former colleague said.

He said that, although Doyle had spoken of the ear-biting incident and being discharged from the Marines, he did not know he had been to prison and believed Doyle had not disclosed it to bosses.

The ex-colleague, who had relatives at the parade in May, said: ‘What happened beggars belief. If you are a supporter in that situation, there’s nowhere to run, you can’t move.

‘Until we spoke to the in-laws, we were so worried.’

He added: ‘Knowing Paul as I do, he’s kind of a loose cannon. 

‘What he did in Liverpool is wrong on so many levels. He didn’t get away with it but he shouldn’t have been painting himself as a victim (by falsely claiming his car was under attack) and should have owned up to what he did immediately.’
