BLOOMINGTON, Ind. - An Indiana University student has been arrested after he threatened a custodian while skateboarding with a sword, police said.

The custodian first reported seeing the student skateboarding on the first floor of the Fine Arts building late Wednesday, the Herald Times reported.

The custodian twice told the student that he could not skateboard in the building, to which he said he could skate if he wanted to, police said.

The student left the building and returned about five minutes later, wielding a 3-foot sword, police said.

"I bet you won't tell me not to get in here anymore," he said, the custodian told police.

Officers found Joseph Masek, 36, on the first floor of the building and the sword in the bed of his truck, police said.

Masek told officers he was messing around and thought the custodian knew he didn't mean any harm, police said.

Masek was arrested on a preliminary charge of intimidation with a deadly weapon.

He was released on bond from the Monroe County Jail on Thursday.
