The Gilroy Fire Department responded to three fires within a span of a day from Feb. 18-19, two of which are being investigated as suspicious.
A fire tore through a bathroom at Christmas Hill Park, as well as an industrial building on the 5900 block of Obata Way, both of which investigators believe were intentionally ignited.
A third fire on the 7200 block of Hanna Street appears to be accidental, according to the fire department.
No injuries were reported, and there appears to be no connection between the fires, officials said.
The Gilroy Fire Department was joined by the Santa Clara County Fire Department and San Jose Fire Department in knocking down the flames.
