At least 11 people were stabbed at a Houston-area college Tuesday, which was on lockdown after the attacks, officials said.
At least four victims at the Cy-Fair campus of the Lone Star College system in a northwestern Houston suburb were taken by helicopter to local hospitals, and more were taken by ambulance, the school said in a statement.
The Harris County Sheriff's Office reported that a suspect had been taken into custody after the incident at the school's Health Science Center.
"A long, extensive investigation on this sprawling campus is being conducted," the department said in a statement.
A lockdown alert posted on the college's website as of 12 p.m. Central time said that there were two armed suspects and that one was still on the loose.
Two hours after that alert, the college remained on lockdown and was under evacuation.
