Four mechanics from a Lancashire garage have been jailed after setting fire to a vulnerable apprentice with a blowtorch.
The teenage victim, who suffers from autism, was bullied and abused by colleagues at a garage in Wesham, near Blackpool.
CCTV footage showed three of the attackers chasing the victim around the workshop, aiming the blow torch and accelerant towards him.
A fourth man leant against a door to prevent the victim escaping the attack.
The offenders eventually stopped and could be seen laughing, having left the victim in pain, police said.
The apprentice suffered burns to his upper thighs and later attended a health centre where he told health workers what happened, with the matter reported to police.
Adam Lavelle, 34, Michael Jeffrey, 31, Soldon Legdani, 23, and Simon Hickinbottom, 45, have been jailed for their role at Preston Crown Court.
Lavelle was sentenced to 18 months in prison, Jeffrey was jailed for 14 months and Legdani for 10 months for section 20 wounding.
Hickinbottom was given 21 weeks in prison for common assault and providing a false statement.
Detective Constable Jordan McDonald, of Lancashire Police said: “This was a horrendous attack which left the victim, a young man with autism, seriously injured.
“The men preyed upon his vulnerabilities, carrying out escalating threats which ultimately resulted in the victim being chased inside the locked garage, cornered by the offenders and set on fire, causing burns to his upper thighs.
“The bullying and abuse was revealed once the victim went for medical treatment, with the police then launching an investigation.
“While workplace bullying is unfortunately commonplace, the actions of these men went far beyond this.
“I am glad each of the men have received custodial sentences and can use their time to reflect on the gravity of their actions and the lasting impact it’s had on the victim.”
