At least three people wounded when gunfire erupts.
Multiple people have been shot at a north Harris County, Texas college, and a second suspect may be on the loose, Harris County Precinct 4 deputy constables said.
Investigators said the shooting happened at Lone Star College's North Harris campus shortly after noon on Tuesday.
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.
Officials have not said exactly how many people have been shot and have not released the extent of their injuries. Ben Taub Hospital said it was expecting two patients. Memorial Hermann Hospital said one person was transported by ambulance.
Deputy constables said they have at least one person detained, but have not said if that person is a suspected shooter.
