Police say they raided a cockfight in a rural part of Dallas, arresting three organizers and sending hundreds of spectators fleeing into the woods.

Police spokesman Jerry Monreal says nearly 400 people who paid $20 admission scrambled as officers broke up a cockfight Saturday at a boxing ring-sized pit. Misdemeanor citations were issued to about 100 who were caught.

The three people arrested face felony charges of engaging in organized crime. Police say they found books used to take bets.

Monreal says officers found syringes they believe were used to inject the birds with steroids.

He says animal control officers took some injured birds.
