Officials say about a dozen people have been wounded in a stabbing attack at Houston-area college campus.
Cy-Fair Volunteer Fire Department spokesman Robert Rasa says 12 people were taken to area hospitals after the Tuesday attack on the Lone Star community college system's campus in Cypress.
The Harris County Sheriff's department confirmed at least 11 people wounded and that authorities have one suspect in custody.
Both agencies say at least four of those injured were LifeFlighted in critical condition. Rasa says several patients refused treatment at the scene.
Lone Star posted an alert on its website just before 12 p.m. warning students of two armed suspects and saying one person remains at large. The alert warned people to seek shelter in a secure location.
A different Lone Star system campus was the site of a January shooting. Two people were wounded, and a 22-year-old man was charged with aggravated assault.
