DELANO (AP) — A California man attending a cockfight has died after being stabbed in the leg by a bird that had a knife attached to its own limb.

The Kern County coroner says 35-year-old Jose Luis Ochoa was declared dead at a hospital about two hours after he suffered the injury in neighboring Tulare County on Jan. 30.

Sheriff’s spokesman Ray Pruitt says it’s unclear if a delay in seeking medical attention contributed to Ochoa’s death. Tulare officials are investigating, and no arrests were made at the cockfight.

Cockfighting is a sport, illegal in the United States, in which specially bred roosters are put into a ring and encouraged to fight until one is incapacitated or killed.
