Texas College Stabbing: One suspect in custody, at least 14 people injured in stabbing at Lone Star College, police say

(CBS/AP) HARRIS COUNTY, Texas - One male suspect is in police custody after at least 14 people were injured in a stabbing incident Tuesday on the Cy Fair campus of Lone Star College in the Houston area, the Harris County Sheriff's Office reports.

The Harris County Sheriff's Office would only confirm that some of the injured victims were stabbed.

Four victims were taken to Memorial Hermann Hospital, two by Life Flight helicopters and two by ambulance. At least one of those patients reportedly has critical injuries.

A witness told CBS affiliate KHOU there were two men running down the hallway and randomly stabbing students in the Health and Science Center.  The station said other victims were reportedly attacked in the technology building.

The station also reported that at least one other suspect is still at large, citing unconfirmed police scanner reports. However, the Associated Press reports Harris County Sheriff's Office spokesman Thomas Gilliland says authorities don't believe a second suspect was involved.

Lone Star officials have confirmed the campus is on lockdown.

"Seek shelter now. If away, stay away," the school reportedly said in a text to students.

"This is an emergency. Everybody stay inside of your rooms. Do not leave your rooms," said an announcement made over the loud speakers of campus buildings.

The station reports students say every car leaving the area is being searched.

Several parents rushed to the campus after hearing about the stabbings, according to the station.

"Basically, I'm frantic. I'm scared out of my mind," one mother whose daughter is locked in a classroom told KHOU. "Even though she's 21, she's still my baby. As soon as she gets out, I'm going to give her a hug and kiss."
