Earlier Harris County Sheriff Ed Gonzalez said on Twitter that multiple agencies were responding to a “possible active shooter incident at a school.”

Live TV footage from the scene showed students crying and holding each other as ambulances with their lights flashing navigated caution tape and law enforcement officials to get to the school.

A statement issued by YES Prep said, in part:

“Police are on campus with a suspect in custody who opened fire inside the school. No students have been injured.”

The school was evacuated and students taken to other schools. Parents were directed to those locations to pick up the children.
