Daiki Minaki, 18, was arrested Saturday night at 9 p.m. after police received several frantic calls from people saying they were attacked by a naked man.
"The next thing I know, there's a naked man running at me," homeowner David Otte said.
Otte will never forget the screams he heard outside his home Friday night. A woman walking her dog was being punched and kicked by a man who was naked. When Otte opened his door, the man charged him.
"To stop him from entering my house I had to kick him in the stomach and he stumbles back, he swears at me, picks up a bunch of mail off the mail table and throws it, screams at me again and runs out of the house," Otte said.
Police believe Minaki was on drugs when he randomly assaulted another man and his son inside their house on the same street. Police cornered Minaki on Otterson Court where he was already bloody from the rampage.
"As soon as the subject was in cuffs, he spit blood on the officers, struggled with officers," Palo Alto police Sgt. Kara Apple said.
Minaki is a senior at Palo Alto High School and a rising star in the martial art of kendo. Those who practice the sport are stunned about his arrest.
"He was going to participate in the US championships in June, yeah so I'm really sorry hearing about that," suspect's friend Takeshi Tokanaga said.
Minaki is out of jail and is back home, which is just a block away from where the attacks happened.
Minaki told ABC7 News he couldn't remember what happened Friday night and claims he blacked out.
The female victim was transported to a local hospital, where she was treated for moderate abrasions and bruising to her face, head, chin, and knuckles. She also complained of pain in her torso. Neither of the male victims sustained any injuries. One officer received scrapes on his hands during the arrest, but did not require medical attention. The suspect had numerous abrasions to his face, legs, and hands, and also had a cut on his face from an unknown source that both male victims described seeing when he entered their homes. The suspect received treatment for his injuries at a local hospital before going to jail.
Daiki Glenn Minaki of Palo Alto was booked into jail for one count of felony battery for his actions against the woman walking her dog, and six misdemeanor charges (resisting arrest, battery on an officer, under the influence of narcotics, battery, and two counts of trespassing).
The suspect was not known by any of the victims, and police believe all three of his attacks were random.
