'Bam' Margera, 'Jackass' star, turns himself in, appears in court on assault charges

POCOPSON TWP., Pa. -- Professional skateboarder and former "Jackass" star Brandon "Bam" Margera turned himself in Thursday morning, days after a warrant was issued for his arrest.

He was fingerprinted and photographed before he was arraigned in a Chester County, Pennsylvania courtroom, troopers said. He pleaded not guilty and was released on bail of $50,000 unsecured.

Troopers first responded to Pocopson Township, Pennsylvania on Sunday morning for a reported disturbance.

They said Margera began punching and kicking his brother's locked bedroom door about 8 a.m., according to the affidavit of probable cause.

As his brother exited the room, police said he found a handwritten note reading, "If you ever (expletive) think of calling the police on me I will officially (expletive) you up."

The note was signed "Bam," police said.

Margera's brother then found him in the kitchen, and police said Margera began "screaming at him and became aggressive," then punched him in the head and grabbed his arm.

Margera then said "I'll kill you. I'll put a bullet in your head," according to the affidavit.

His brother then said Margera threatened to kill everyone in the house, police said.

Margera then fled from the home and into the woods. Troopers searched the area, but Margera could not be found.

He is now facing charges of assault and terroristic threats.

His attorney Michael van der Veen says he hopes to get him an acquittal.

"He pled not guilty. He was given a bail of $50,000 unsecured, which means he didn't have to post any money and he's free to travel around and conduct his business," said van der Veen. "Families have disputes like any family. That's what this case is about, it doesn't belong in the courts."

As part of his supervised bail, Margera is not allowed to leave the state, have any contact with the victim or return to his home where the fight happened.

He must also undergo a drug and alcohol evaluation and comply with the recommended treatment plan.

The professional skateboarder has struggled with substance abuse in the past, but his attorney would not confirm or deny if he is seeking treatment at a rehab facility.

"Over the last couple days I've had a lot of contact with my client and he seemed clean and sober. There was no rampant drug use of any kind," said van der Veen.

A preliminary hearing is now set for May 25.
