A man with a cow slurry fetish has been jailed for five years after threatening to kill a family who tried to stop him targeting their farm.
David Truscott, 43, repeatedly rolled around naked in cow slurry and developed an obsession with a farm in Redruth, Cornwall.
Exeter Crown Court heard that Truscott, formerly of Camborne, Cornwall, targeted the property over an eight-year period to indulge in his bizarre fetish.
He initially removed cow pats from the farm but his behaviour escalated, with Truscott regularly entering Woodbury House Farm to masturbate in slurry.
Truscott was handed an extended sentence of 10 years following psychiatric reports.
Judge Philip Wassall told Truscott: "When the family took steps to clear up the slurry from the cattle to prevent you from wallowing in it and took other measures to stop you getting on to their land, you began these offences.
Prosecuting, Eleanor Purkis said: "The defendant has a fetish in relation to animal faeces.
"His behaviour has escalated from initially removing cow pats from the farm to attending the farm and masturbating in slurry."
Truscott was jailed for three years at Truro Crown Court in 2005 after setting fire to the Roth's tractor, hay, a pen containing cattle and wooden fences.
In September 2009, he received a 16-week sentence after he stripped naked in the cattle pen, released the cattle and climbed into the slurry spreader.
On his release, Truscott returned to the farm and sat naked in cow muck. He was jailed for a further 20 weeks.
He was jailed for two years in September 2011 after police caught him naked in a field harassing the Roth family.
