(Reuters) - Three people were injured at a college near Houston, Texas on Tuesday after shooting broke out between two people on the campus, police said.

One of the shooters was in police custody and the other fled the campus of Lone Star College, according to college spokesman Jed Young. He said it was not clear if they were students.

"The school is under control but still under evacuation," Young said.

The shooting occurred just over a month after a gunman killed 20 students and six staff at an elementary school in Newtown, Connecticut.

The Lone Star College System is the largest institution of higher education in the Houston area, according to its website. Student enrollment is 90,000 and there are six colleges in the system.

There have been three separate shootings at schools and colleges in the United States in the past two weeks.

On January 10, a student armed with a shotgun opened fire at a California high school, wounding a fellow student. A second student also received minor injures at Taft Union High School in Taft, California, about 30 miles southwest of Bakersfield.

On January 15, a student armed with a pistol opened fire at Stevens Institute of business & Arts in downtown St. Louis, shooting a school employee and then turning the gun on himself.

Also on January 15, two people were killed and a third wounded when gunfire broke out in the parking lot of a community college in eastern Kentucky. Authorities said that shooting was a result of a domestic conflict.
