PORTREE, Scotland (UPI) -- A drunken gatecrasher at a black-tie ball has been convicted of assault after he head-butted an organizer of the Portree, Scotland, event.

Angus MacQueen, 34, was found guilty in Portree Sheriff Court of assault after he forced his way into the Skye Ball at the Sky Gathering Hall and head-butted organizer Alasdair Hilleary, 54, on his nose, The (Glasgow) Daily Record reported.

Hilleary told the court MacQueen "seemed to be spoiling for a fight."

"The head-butt caused quite a lot of blood but did not break my nose. I did not need medical attention. I stood my ground and did not respond," he said.

Booze what it can do to a person
