HOUSTON, Texas (CNN) -- A man with a gun entered a building on the sprawling campus of Johnson Space Center Friday, forcing the evacuation of the building and putting the entire center on alert.
A witness reported two shots fired, said Houston Police spokesman Capt. Dwayne Ready, who described the suspect as a white man with blond hair, about 5 feet 9 inches and 50 to 60 years old. He is armed with a handgun.
"He's barricaded himself into a room," Ready said. "We're not going to know anything more until we establish communication."
Ready could not confirm whether there were any hostages or injuries.
The gunman is in Building 44 on the Johnson Space Center property, police said. Building 44 holds a laboratory.
The call for help came in to the Houston Police at 1:40 p.m. (2:40 p.m. ET) but it's unclear who made that call. (Watch employees being evacuated after gunfire is heard Video)
There is "extremely tight security" at Johnson Space Center, NASA spokesman James Hartfield said.
A NASA spokesperson told CNN that all employees have been told to go home for the day.
Space Center Intermediate School, less than a mile south of Building 44, was locked down, said Karen Permetti, spokeswoman for Clear Creek Independent School District. The lockdown was lifted at about 4 p.m. (5 p.m. ET).
The school has about 1,200 students, according to the school district.
As standard procedure, Mission Control's doors were locked, The Associated Press reported.
