BOZEMAN, Mont. -

A methamphetamine lab is suspected as the cause of a small explosion in a room at a Bozeman motel.
Bozeman Police Capt. Steve Crawford says officers received a report of a possible explosion and fire at the Continental Motor Inn at 8:50 p.m. Tuesday.
Crawford says the small explosion blew out the window and slightly damaged the door of a second-floor room. He says there was no fire damage and no one was hurt.

During the investigation, police arrested Devon Arnaud for a probation violation, citing illegal drug use.

According to court papers Arnaud is being investigated for operating a clandestine meth lab. His bail was set at $100,000.

The Continental Motor Inn is still allowing guests to stay in rooms adjacent to the damaged room.
The Missouri River Drug Task Force continues to investigate the incident.
