HOUSTON (AP) — A shooting on a Texas community college campus wounded three people Tuesday and sent students fleeing for safety as officials placed the campus on lockdown, officials said.

Harris County Sheriff's Maj. Armando Tello said authorities had detained a person of interest. He did not provide any details about the people who were wounded, such as whether they were students or included the person who was arrested.

Authorities thought there could be a second shooter, according to a law enforcement official in Washington who spoke on condition of anonymity because he was not authorized to discuss the ongoing case.
