Officials are calling Saturday night's raid in Lewis County, Tenn., one of the largest illegal animal fighting rings of its kind. Hundreds of people were arrested at a cock fighting ring near Hohenwald, Tenn. Authorities said close to 300 people were in attendance, and 37 of them were cited for drug charges and more than 230 were given citations as spectators. Authorities also seized $30,000 in cash and said 220 birds were on hand for the day's events.

Tennessee is part of what is called the cock fighting corridor, which also includes Alabama, Kentucky and Mississippi. Cock fighting is prevalent in those states because penalties aren't stiff enough to discourage participants. Even those who bring chickens to the fight are only charged with a class A misdemeanor. Spectators cited at the event could receive a $50 fine.

The USDA's Office of Inspector General led the investigation, which also involved the FBI, Tennessee Bureau of Investigations and the Tennessee Highway Patrol.
