Fourteen people were injured in a stabbing incident Tuesday at Lone Star College's CyFair campus in Cypress, Texas, a Harris County sheriff's spokesman said -- an incident prompting officials to urge students to take shelter. Authorities have detained one suspect -- so far the only suspect at this point, the sheriff's spokesman told reporters Tuesday afternoon. "At least four were transported by (helicopter). A suspect is in custody. The campus is on lockdown," the sheriff's department said in a news release.
