Deputies seized 40 cockfighting roosters during the bust, but Animal Services euthanized the roosters, saying it does not adopt cockfighting roosters.
The location of the cockfighting operation was at a property in the 100,000 block of 72nd Avenue in Riverside County near the Imperial County border.
Deputies and officers cited about 30 people for attending a cockfight, which is a misdemeanor.
Animal Control says usually in these operations, people scatter. However, the Sheriff's Department's presence was so well coordinated with off-road and quad vehicles that not many people escaped.
"It sends a message to those who attend these illegal fights, that we're taking them very seriously," said Sgt. James Huffman of Riverside County Animal Services.
