Los Angeles County firefighters made short work of a fire that broke out at the Pitchess Detention Center shooting range in Castaic on Sunday morning.

The fire was first reported at 9:50 a.m. at the 29000 block of The Old Road in Castaic and firefighters were on scene by 9:57 a.m.

The fire was located at the shooting range of the Pitchess Detention Center, and at this time, officials did not release the reported cause.

The fire reached a size of about a half of an acre, but firefighters were able to quickly get it under control.

The fire was extinguished at 10:14 a.m. less than 20 minutes after responders first arrived on scene, due to relatively light fuel for the flames.

No structures were threatened by the fire and no injuries have been reported.
