Law enforcement authorities said three people were wounded and a person of interest was detained in a shooting at a Houston-area community college.
KPRC-TV in Houston reported that a second suspect remained on the loose.
Investigators said the shooting happened at Lone Star College's North Harris campus, 2700 West W. W. Thorne Drive near Aldine Westfield, shortly after noon on Tuesday.
Ben Taub Hospital said it was expecting two patients. Memorial Hermann Hospital said one person was transported by ambulance.
Reginald Neal said his nephew, Jody Neal, 24, was one of the wounded taken to Ben Taub Hospital.
"All I know he got shot three times. That's all I know," Reginald Neal said. "He got shot in one of his arms, in the stomach and the leg."
"He was sitting in the study room. There (were) three people on the computer and a guy walked up the stairs and opened fire on him," said Stacy Neal, Jody's sister. "They said it was just one guy that came in with a gun."
Some students said two men were involved in a dispute in the library and both pulled out guns and began firing at each other. Law enforcement officials have not confirmed those accounts.
Deputies said they have detained a person of interest. Investigators said a suspect, an 18- to 20-year-old black male wearing a red shirt and Falcons cap, fled north of the campus to a nearby subdivision. Deputies are actively searching for him.
"I was waiting for my English class to start. It was five minutes before class and all of a sudden, I heard shots fired and people started rushing in the hallway. A few students even came in to our room seeking shelter and we closed the door and we pushed the table against the door and we were hiding," student Amanda Vasquez said. "You never think this is going to happen to you."
Vasquez said the shots seem to be fired in her classroom's hallway.
"They sounded very close -- the shots. (We heard) five or six gunshots," Vasquez said. "I just ducked under the table as fast as I could and hoped for the best. I saw one of the shooters when he was already under police control."
Armed Harris County sheriff's deputies searched buildings and vehicles for anyone who may be involved in the shooting.
A shelter-in-place was ordered at the college, but the campus was evacuated a short time later. The campus is closed to the public.
Aldine Independent School District officials said four nearby campuses, Dunn Elementary, Parker Intermediate, Nimitz 9th grade campus and Nimitz High, were placed on lockdown as a precaution. School district officials said there is no reason to believe a shooter is on any of those campuses, but the lockdown was issued for precautionary measures.
Lone Star College's North Harris campus sits on 200 acres and opened in 1973. It offers more than 80 programs of study.
