At least two people have been shot at Lone Star College in Houston, Texas on Tuesday. At least one person has been detained, and a second suspect may be on the loose, according to Click2Houston.com.

The shooting took place near the university's cafeteria and possibly also the library, reports Houston's local ABC affiliate, KTRK. Footage showed at least two people being wheeled in ambulances, reports CNN.

"The two victims, we're told, have suffered multiple gunshot wounds, but were conscious when they arrived at hospitals," says KTRK. "Both have been taken into surgery. Medical crews could be seen tending to at least three victims outside buildings on campus."

SWAT teams are in the process of evacuating students from several buildings on campus, Yahoo!'s The Lookout blog reports, and four nearby elementary, middle school, and high school campuses have been placed on lockdown as a precaution.

A witness told CNN affiliate KPRC "that she hid under her desk while she heard five or six gunshots."

Agents from the FBI and from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) are both on the scene to assist local authorities.

The school posted an alert on its website warning students to take shelter. "LSC-North Harris is locked down," the school said. "Students, faculty and staff are advised to take immediate shelter where you are. Do not enter the campus until notified further."

Recent reports from KHOU in San Antonio suggest that a third person may have been shot, and that one of the shooting victims may have been a suspect.
