Brush fire near Chino state prison burns nearly 30 acres
A brush fire on the grounds of the California Institution for Men in Chino burned between 25 and 30 acres Friday afternoon but is mostly contained, authorities said.
Prisoners were put on lockdown when the fire began and will remain so pending an investigation of the blaze, authorities said.
Preliminary information suggests the fire was caused by a prison vehicle that malfunctioned near dry vegetation, prison spokesman Lt. Dirk Williams said in a news release.
The fire briefly threatened two buildings at the prison, but no structures were damaged, said Chino Valley Fire District spokeswoman Massiel Ladron De Guevara. It is 60% contained.
The prison, which houses nearly 5,000 inmates, has four facilities spread out over 2,500 acres, Williams said.
