A woman who doused a bed in petrol and set it alight while her former lesbian lover lay naked with a new girlfriend was jailed for five-and-a-half years today.

Jealous Sarah Metcalfe, 47, of no fixed abode, discovered her ex-girlfriend Katie Wrigglesworth in bed with Emma Shakesheff in a caravan she owned at Goldsbrough Mill Farm, near Knaresborough, North Yorkshire.

The court heard how Metcalfe set fire to the bedroom in a desperate bid to stop her former lover and Miss Shakesheff having sex on July 20 last year.

Metcalfe was sentenced to five-and-a-half years at Leeds Crown Court after earlier admitting a charge of arson, being reckless as to whether life would be endangered.
