Authorities have launched an investigation into a farm that allegedly promoted itself as a haven for animal sex.

James Tait, 58, who was convicted in 2005 of trespassing on a neighbor’s ranch to allegedly have sex with horses– was charged with three counts of felony animal cruelty. Kenny Thomason, who lives with Tait in Maury County, TN was also charged with two counts of the same offence.

“They’ve been having sex with full-grown horses,” Maury County Detective Terry Chandler.

“(Tait) has been here for four years, and it looks like it has been going on for some time.”

Det. Chandler said the pair lived on the farm owned by Mr. Thomason, which housed 13 horses, Shetland ponies, goats and dogs.

The detective said it was suspected people had been having sex with the ponies and dogs, as well as the larger horses.

Police were tipped off after an anonymous person who had visited the alleged sex farm emailed authorities photos of a man engaged in sex with an animal.

Authorities had also discovered several video tapes explicitly showing men performing the acts on the farm animals leading them to believe it could be a haven for animal sex.

Both Tait and Mr Thomason are each being held on more than $100,000 bail.
