Jose Alfredo Yanez was released from West Valley Detention Center in Rancho Cucamonga at 11:28 a.m. Monday, according to sheriff's jail logs. He has no court appearances scheduled.
Fontana police booked Yanez, 49, at the county jail shortly after 3 p.m. Sunday on suspicion of cruelty to animals.
Police broke up the elaborate ring at a large commercial-trucking company in the 15700 block of Boyle Avenue in Fontana after getting an anonymous call about 8 a.m., officials said in a press statement.
Yanez was arrested at 15732 Boyle Ave., the address for a trucking company, according to jail logs.
No one answered the phone late Monday at the trucking company. The voice-mail service said it was full and would not allow a message to be left.
Police said in their statement that several birds were confiscated, and several arrests were made.
A Fontana police spokesman could not be reached Monday for comment about the arrest.
San Bernardino County prosecutors took aim at cockfighting and the impact it has on communities in a video posted on YouTube in December.
The goal of the District Attorney's Office, which produced the video with help from the Humane Society of the United States and Fontana Animal Services, is to increase awareness about the dangers of cockfighting and inform people about whom to call if they see the activity in their neighborhood.
A reward program is available for tips that lead to arrests and convictions. The District Attorney's Office said in December that it had prosecuted 43 cockfighting-related cases over the past year and that more than 400 roosters were seized.
The bust on Sunday was not Fontana's first brush with cockfighting.
In August, 300 roosters were rescued from a Fontana site that bred the birds for fighting, according to the district attorney's video. Officers found special blades attached to the roosters for fights.
Several months earlier, a Fontana man was arrested after he allegedly made thousands of dollars while operating an unlicensed dental office and a cockfighting arena out of his backyard.
Luis Rosales was arrested last April at his home, which rests on about four acres in the 11100 block of Cypress Avenue. Officers said they found hundreds of fighting roosters there.
