At least three people were hospitalized after gunfire erupted on the campus of Lonestar College in Houston, Texas Tuesday.
Authorities say two of those rushed to nearby hospitals suffered gun shot wounds.
Witnesses say an argument between two men in the school's library escalated into a gun fight.
"We heard six shots and automatically we heard students running and we automatically went under our desks, our teacher shut down the lights, and we took cover," one student said.
Investigators say those wounded were caught in the crossfire.
Police took at least two "persons of interest" into custody shortly afterward.
