A man savagely killed a dog, ran naked through a tennis club and poured hot coffee on his head before he was finally arrested early Wednesday, Orange County sheriff's deputies said.

Bayron Reyes Lopez, 26, of San Clemente, was hospitalized after being captured at the tennis club where he worked as a maintenance man, sheriff's spokesman Jim Amormino said.

Deputies got the first call about the man at 4:30 a.m. Wednesday when there were reports of a loud radio at his apartment. Amormino said deputies believe he jumped from a third-story window to get away, and was unhurt.

Just after 6 a.m. Judy Donnelley called to say a "strange" man had approached her, and when her 5-year-old mini schnauzer named Coco intervened, the man killed the dog, hitting, choking and "repeatedly beating her on asphalt in front of me."

"She saved my life," Donnelley told KCAL-TV. "I don't know how to thank her." She put flowers on the street where her dog died.

Minutes later, other callers reported a naked man running through the Rancho San Clemente Tennis Club and pouring hot coffee on his head. That's where deputies caught up with him, Amormino said.

He was initially hospitalized but "will be, at the least, booked for cruelty to animals," Amormino said.

He was being tested to determine if he was under the influence of any drugs or narcotics, Amormino added, so other charges were also possible.
