(CNN) -- A man possibly armed with explosives took at least one hostage Wednesday at the headquarters of the Discovery Channel in Silver Spring, Maryland, police said.
Capt. Paul Starks said that police were in communication with the gunman, and that he was making some demands. The suspect had "concerns" with the Discovery Corporation, he said.
A caller from One Discovery Place, the channel's headquarters, called police about 1 p.m. to report a man with a gun and possible explosives, said Angela Cruz, a police spokeswoman.
The area has been evacuated, she said.
I actually just saw this on the local news when I turned on the tv. They had more informaton too, such as the suspects name and that his permanent residence is in california, but he spends a lot of time here, and the fact that he staged a protest two years ago against discovery for things such as "glorifying overfishing and builders of pollution machines." Was arrested for that protest on disorderly conduct charges.
The hostage situation is still on-going.
