A building at NASA's Johnson Space Center has been evacuated after reports of a man with a weapon, according to news sources.
Houston's Local 2 reports, based on police communications, that "shots were fired" at Building 44, but NASA has yet to confirm that. A SWAT team is also at the scene, according to the Houston Chronicle.
A NASA subcontractor with offices in the building, Jacobs Engineering, has stated that the gunman, who has been confined to one room, is an employee of theirs, Local 2 says.
It is not yet clear whether there have been any injuries. A nearby school was under precautionary lockdown but has now been reopened, according to Local 2.

The alert comes only days after a gunman shot and killed 32 students and staffers at Virginia Tech, and on the eighth anniversary of the Columbine High School massacre.
