PARKER, Colo. -- South Metro Fire Rescue worked to battle a fast-moving brush fire in Parker on Thursday afternoon that investigators said was "human caused and suspicious."
The fire burned 14 acres after being brought under control about 3:15 p.m., Ponderosa Fire said.
The fire burned in a wildland area between South Parker Road and Jordan Road, south of East Pine Lane.
Officials initially said it was too dangerous to send in firefighters on foot.
"Firefighters unable to make a direct attack due to extreme fire behavior," South Metro Fire said on Twitter.
There were 75 personnel and 36 units from five departments working the fire, and a helicopter was called in to make water drops.
At 1:45 p.m., the Parker Police Department said the water drops were still underway.
Roads were closed in the area and one school was put on lockout so crews could use the parking lot as a command post.
No homes were threatened and there were no evacuations required.
Crews from South Metro worked to burn off the fuel in front of and on the flank of the fire to stop its spread.
There were no reports of any injuries or any damage to any structures.
