Sky News: YouTube videos of two American employees calling themselves Kirsty and Michael appeared online on Tuesday.

It seemingly shows the male staffer passing wind on a sandwich and putting cheese up his nose.

They claim in the video the food would be served to customers.

A spokeswoman for Dominos told Sky News Online the pair had been sacked and the police had issued an arrest warrant.

The firm will also file a civil suit, she said.

"He just farted on that salami that goes on the sandwich," Kirsty can be heard saying as she films her colleague.

"In about five minutes they will go out on delivery and people will be eating these and little do they know the cheese was in his nose."

Within hours, web users had managed to locate the US drive-through and contacted the firm's head office.

The spokeswoman said the pair claimed it was a prank and the food was never served.

"Dominos is not in a forgiving or forgetting mood right now. It is not acceptable," she told Sky News Online.
