(CNN) — Officials believe two students were wounded in crossfire as two people shot at each other at a Texas community college Tuesday, a school spokesman said.

One of the shooters was also injured and is in custody at the North Harris Campus of Lone Star College, spokesman Jed Young said. The other shooter fled the campus, he said.

“The police believe the danger has been mitigated,” Young said. “The school is under control but still being evacuated.”

There were more than 10,000 students at the campus at the time of the shooting, Young said.

“Please don’t go to campus! If you are on campus. Use caution!” a post on the school’s Facebook page said.

Police and emergency responders swarmed an entrance to the campus, aerial video from KPRC showed.

Medical personnel were seen treating at least two people and moving them to ambulances. Students were jogging away from some buildings, with their hands up in the air, presumably in response to police instruction.
