An insane man from the Philippines who has been described as the 'world's deadliest serial animal rapist', Andy Loyola, has been arrested after a farmer caught him having sex with one of his cows, according to Abc-cbnnews reports.

The 46-year-old Loyola, is reported to have raped several animals including cattle, horses, buffaloes, goats, as well as getting a cow pregnant.

The farmer, Rustico Sarno, said he caught Loyola red handed having it with his cow which had gone missing from his farm.

Sarno has previously accused him of raping his cattle, along with other animals, on numerous occasions.

Police believe Loyola was under the influence of drugs during his latest assault. Officers obtained various drug paraphernalia when they arrested the man last week.

Sarno also claimed that the cow rapist impregnated the cow during the assault. According to Sarno, that particular cow had not yet mated with a bull, making Loyola the only possible option.

Authorities plan to test the cow to learn the origins of the cow’s pregnancy.
