BOISE, Idaho (CBS2) — The Ada County Sheriff's Office reports that a 21-year-old Boise man caused quite a disturbance at a gym in Eagle after he intimidated two teens, knocked himself over with the front door, then broke a plate glass window with a large knife.

The incident occurred Sunday afternoon at the northeast shopping center of Eagle Rd. and Highway 44. A man identified by police as Jacob Roberts, allegedly was seen intimidating two teen boys while they were exercising in the gym. An adult woman put herself between the two teens and Roberts, telling him to leave them alone.

Reportedly the two teens and the adult woman barricaded themselves in a mat room using kettle bells to block the door. Witnesses told police that Roberts then became visibly more agitated by not being able to get in to the mat room. Roberts attempted to flee as bystanders called the police. He ran headlong into the front door, knocking himself backwards. Apparently frustrated by this, Roberts pulled out a large knife and used it to break a plate glass window, creating his own exit.

A large police response led to a brief manhunt, identifying and locating Roberts roughly 30-minutes later. As the deputies pulled Roberts from the patrol car to book him into the Ada County Jail, he attempted to run. Roberts reportedly attempted to bite one of the deputies during the ensuing scuffle. He now faces felony charges for malicious property damage and assault with the intent to commit serious injury, and a misdemeanor charge of resisting arrest.
