HOUSTON, Texas (CNN and Reuters) -- NASA evacuated a building at the Johnson Space Center in Houston after a person with a gun was seen and a shot was fired, a NASA spokeswoman said Friday.

NASA Spokeswoman Brandi Dean said it was not yet known if anyone was hurt. Local police were on the scene, she said.

Another NASA spokesperson, James Hartfield, told CNN there were gunshots heard in the building. A call for help came in at 1:40 p.m. (2:40 p.m. ET) to which Houston police responded.

Hartfield said all of the employees that would have been in that building have been evacuated.

There is "extremely tight security" at Johnson Space Center, said Hartfield.

"A person would [have] to have some sort of I.D. and security card [to enter],"
