The arrests happened around 11:30 p.m. Saturday in the 4700 block of N. Counts Boulevard, a rural road near Loop 12 south of Interstate 30.

A press statement from Dallas Police say when officers arrived they found a large amount of cars parked in a field off Counts Blvd.

Upon investigation the officers found the fighting ring, which is illegal in Texas due to gambling that takes place and the cruel treatment of the animals.
