Four people were arrested this week for allegedly beating a San Ramon man after he confronted them for being too loud in his neighborhood, police said.

The victim, Casey Pletz, said late Friday night he heard the four young men yelling outside of his home, near Walt Disney Elementary School at Pine Valley Road.

"Just being loud in the middle of the night," Pletz said.

When the noise increased and got closer to his home, the 23-year-old Pletz confronted the group and told them they needed to leave.

Instead, Pletz said one of the suspects, later identified as 19-year-old Jordan Manibusan, started beating him.

Manibusan, a jiu-jitsu fighter, would not stop.

"So I ended up getting choked out until I was unconscious," Pletz said.

Another person, later identified as 20-year-old Zachary Kennedy, and two juveniles also got involved, according to Pletz.

"They proceeded to kick me in the face and body," Pletz said.

He suffered a broken nose, a bruised kidney, a fractured cheekbone and several cuts and bruises.

Neighbor Kellie Schultz saw the attack from her porch before another neighbor stepped in.

"If our neighborhood hadn't come out, I think that he could have been killed," Schultz said.

Pletz said the neighbor who came to help scared the attackers off and saved him.

Police on Thursday said they arrested all four suspects in the past 24 hours.

Manibusan was arrested Tuesday when police served a search warrant at a San Ramon home. He was arrested on suspicion of assault with a deadly weapon and felony battery.

Manibusan was booked into the county jail in Martinez on $80,000 bail, according to police.

On Thursday morning, officers arrested Kennedy, a Danville resident, on suspicion of assault with a deadly weapon and felony battery.

Kennedy is also being held on $80,000 bail.

Also on Thursday morning, police arrested two 17-year-old San Ramon residents on suspicion of the same offenses as the two men, police said. The youths are being held in the county youth detention center in Martinez.

Meanwhile, Pletz, a professional skier and skateboarder, is focusing on recovering.

"I am doing alright though, healing," he said. "It's all a matter of time now."

A GoFundMe account has been set up to help Pletz pay for his medical bills.
