The attack about 11:20 a.m. on the LoneStarCommunityCollege System's campus in Cypress sent at least 12 people to area hospitals, including four taken by helicopter, according to Cy-Fair Volunteer Fire Department spokesman Robert Rasa.
The LoneStarCollege system is the largest institution of higher education in the Houston area, and the fastest-growing communitycollege system in Texas, according to its website.
