Colorado Springs firefighters have contained a grass fire in the area near Coronado High School. The fire was burning in the area of Fillmore Street and Farnham Point.

The fire is now reportedly in the "mop up" stage and no longer growing. 12 acres have burned according to fire crews.

Right now firefighters don't know the cause, but they say students from the high school will often cross the street to that field to smoke cigarettes. Investigators are questioning 3 people, a bus driver, a high school student and a junior high student.

A spokesperson from the fire department says the fire did not directly affect activity at the school.

No homes were evacuated or threatened.
