A paper towel dispenser was set on fire in a bathroom at Haas Pavilion Sunday night, causing little damage.

At about 11:35 p.m., UCPD officers responded to a fire alarm activation at Haas Pavilion, and upon arrival at the scene, they discovered that the fire sprinkler system in the men’s restroom on the ground level on the north side of the facility had been activated by the fire, according to UCPD Lt. Alex Yao. The fire had been extinguished before officers arrived at the scene.

According to a UCPD crime alert, the fire charred and melted the paper towel dispenser and damaged the wall around the dispenser. Some of the water from the sprinkler system had flown into adjacent hallways and onto the men’s basketball court, though Herb Benenson, assistant athletic director for communications, said there was no damage to the court.

Benenson said there was some water damage to the ceiling of the track and field office located directly beneath the bathroom, but said he did not yet know the cost of the damage.

He added that the bathroom will be repaired in time for Friday night’s men’s basketball game and that track and field staff were allowed back into their offices Monday afternoon.

The department is currently investigating the incident as an act of arson, Yao said.
