A transvestite had sex with a dog while its owner was out of sight walking at a romantic English Heritage castle in Cornwall.

The cross-dresser was taking a stroll in the dry moat of Henry VIII’s Pendennis Castle overlooking Falmouth Bay when a walker’s pet bounded up to him.

Realising the pooch’s owner was out of sight, the man mounted the animal for a spot of passion.

However, the owner spotted the incident and the perpetrator ran away, only to be caught and restrained by castle staff.

The man gave a “full and frank confession” before being cautioned for outraging public decency.
