LAYTON — An 18-year-old Northridge High School student was arrested Monday after allegedly starting a fire in a bathroom at the school.

Paul Robles, of Sunset, was arrested for investigation of aggravated arson and criminal mischief in connection with the fire that broke out around 9:50 a.m., Layton Police Lt. Garret Atkin said. The fire started in a restroom at the school, located at 2530 N. Hill Field Road.

Atkin said the room filled with smoke before firefighters with the Layton Fire Department extinguished the fire. An investigation revealed that the cause of the fire was a roll of toilet paper that was lit on fire from inside a plastic dispenser.

"The fire caused damage to the restroom, but nobody was injured," Atkin said. "The school was evacuated for approximately 45 minutes as a precaution."

Robles was arrested as a result of the investigation into the incident.
