OASIS, Calif.—Authorities in Southern California have killed 134 roosters that were discovered in the small town of Oasis during an investigation into a cockfighting ring.

The Desert Sun reported Friday (http://mydesert.co/IRXo2L) that Riverside County sheriff's deputies also uncovered about 10 boxes of blades used in cockfighting, a cockfighting ring and a large trophy.

John Welsh, a spokesman for the county's Department of Animal Services, says the birds were located after someone called in a report of animal cruelty.

The owner was not arrested but could face $3,000 in fines and citations.

Welsh says the birds had to be killed because they had been raised to be aggressive and couldn't be introduced into a normal farm population.

Oasis is about 120 miles southeast of Los Angeles and is located near Palm Springs.
