The fire that destroyed a coffee kiosk on the Davis campus April 30 is being treated as arson.

The UC Davis Police and Fire departments, and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives are investigating the fire. Items from the scene have been sent to the federal agency's crime lab in Sacramento for analysis.

The fire at the Cargo Coffee Co. kiosk outside King Hall was reported just before 6 a.m. April 30. Campus and city of Davis fire units arrived within minutes, finding the wood structure engulfed in flames. There were no injuries.

The Bureau of Alcohol, Tobacco, Firearms and Explosives also is assisting in the investigation of a suspicious object found May 1 at the Cargo Coffee kiosk outside Olson Hall.

The small device, which authorities said could potentially have caused a fire similar to one that destroyed the King Hall kiosk, was reported at 5:30 p.m. Authorities briefly evacuated six buildings in the vicinity, affecting six people at that hour on a Saturday.

The Yolo County Bomb Squad used a robot to examine the device, eventually rendering it safe.

Cargo Coffee also owns and operates a kiosk between Engineering III and Academic Surge.
