Penn State police said they arrested a drunk student armed with an illegal handgun, a knife and a baton in the audience at Phantom Planet's Movin' On performance on the HUB lawn Saturday night.

Isaiah R. Houston, 137 Creekside Drive, was charged with public drunkenness, resisting arrest and possessing prohibited offensive weapons.

He was arraigned before Magisterial District Judge Thomas N. Jordan and placed in Centre County Correctional Facility in lieu of $10,000 straight bail. He was still in prison as of 4:30 p.m. yesterday.

Police approached Houston after "a report from citizens that they saw him wearing a firearm," Lt. Bill Moerschbacher said.

A struggle ensued "very quickly upon walking up to him," Moerschbacher said. He said two officers wrestled Houston to the ground and handcuffed him.

Police said they discovered a knife and baton on Houston after he was arrested. They also determined that the handgun was illegally possessed, Moerschbacher said.

Moerschbacher said Houston did not take out the firearm before or during the struggle.

"He didn't threaten anyone with the firearm or anything," he said. "The struggle is really what precipitated that arrest and discovering the other items."

Jameela Truman, director of Movin' On, said she witnessed the arrest.

She said she felt threatened by the event, but the police "fully handled the situation."

Possessing a firearm is illegal on campus, Moerschbacher said. However, he said if the handgun is legally registered, police will ask the owner to leave or surrender the gun to the police. If the handgun is illegal, police will arrest the possessor, he said.

"It's not normal that we get into a tussle with someone over one, but it does happen," he said.

Moerschbacher said the concert was relatively calm other than Houston's arrest.

"I don't think there was anything out of the ordinary or even bad," he said. "[Movin' On] has changed over the years, and it hasn't been as bad."
