At least three people were wounded Tuesday in a shooting at a community college campus in Texas, according to HLN affiliate KPRC.
The shooting occurred shortly after noon (1 p.m. ET) at Lone Star College's North Harris campus, located 20 miles north of Houston. Lone Star College spokesman Jed Young said two people were arguing with each other when they exchanged gunfire.
At least three people were wounded in the crossfire and taken to area hospitals. There is no word yet on their condition or the extent of their injuries. Officials said a fourth person on campus suffered a heart attack.
Students, faculty and staff on campus were advised through a campuswide alert to take immediate shelter.
Authorities said a "person of interest" has been detained. According to KPRC, investigators are searching for a second suspect who fled north of campus to a nearby subdivision. That suspect is described as being a 18- to 20-year-old black male wearing a red shirt and Falcons cap.
According to the school's Facebook page, the campus has been evacuated. All schools in the nearby area have been placed on lockdown. FBI and ATF agents are on the scene.
