A terrified teenage girl who had fallen asleep at a party woke up to find her hair had been set on fire.
Preston Crown Court heard the 17-year-old victim had been attending the all-day gathering in Fleetwood when the events of the afternoon became too much for her and she dozed off on a couch.
But a judge was told defendant Robert Stockell, of Lingfield Road, Fleetwood, preyed on her defenceless state, setting her hair ablaze and leaving her with horrific injuries.
Police today said the youngster was lucky to be alive following the cruel attack.
Det Sgt Kev Wright, of Fleetwood CID, said: “This was a callous attack on a sleeping girl, which left her with serious injuries.
“Stockell’s actions were dangerous and could have put a life at risk.”
The court heard how the 21-year-old defendant had used a cigarette lighter and an aerosol can to light the youngster’s hair.
She suffered second degree burns to her hand, arm and shoulder as a result of his actions.
Stockell was found guilty of grievous bodily harm after a trial earlier this year.
Describing the incident as a “drunken prank”, Det Sgt Wright said a custodial sentence was inevitable.
He added: “The girl had to attend hospital and, naturally, was deeply shocked to awake and find she had been attacked in this callous way.
“I hope this serves as a warning to others who may think a drunken prank will have no consequences.
“It could end up with a prison sentence.”
