Student arrested after having sex with sheep had the world's most bizarre excuse

California: The 23-year-old was arrested after another student called police after hearing strange noises coming from a nearby barn

A university student has admitted having sex with a sheep on campus because he was 'stressed'.

The 23-year-old, who has not been named, told police he had gone to the university's barn after a night of heavy drinking because he was under pressure with a big exam on the horizon.

His plan or so he claimed was to beat up some cows.

But unbeknown to him, his bizarre antics were overheard by another classmate who immediately contacted police.

Officers apparently found him on top of the sheep with his pants down in the barn.

And all the unidentified fifth-year computer engineering student, at Frenso State University, California, US, could muster to say was: "Am I going to be expelled for this?"

The student, who has been charged with bestiality, initially told police he was wrestling with cattle, according to KMPH Fox 26.

But once told there were no cows in sight he referred to the sheep and said it was "all the same."

He then altered his story, explained about his exam and said he went to beat up the defenceless animal to let off some steam, according to a police report.

Finally, after being told by an officer that he was seen holding the sheep down while wearing no pants, did he admit he was having sex with the poor animal  - but he did say it was his first time.

Vets and animal experts are now keeping a close eye on sheep at the farm.

The incident has since become an internet sensation, with a parody Twitter account being set up named "Fresno State Sheep".
