James Jay Lee, a radical environmentalist with a gun, a grudge and possibly carrying an explosive device, is holed up at the Discovery Channel headquarters in Silver Spring, Maryland, taking hostages and demanding to speak with executives.

Lee recently published a manifesto listing demands to the network, including to stop "encouraging the birth of parasitic human infants." Lee also lashes out about the Discovery Channel programs promoting war and technology.
After he entered the building earlier today, an employee told a local TV station, "We heard, pop, pop, pop, pop." A day care center in the building has been evacuated.
The SWAT team is on scene, where the drama has been unfolding since 1 p.m. Lee is still holding hostages, a small group whose specific numbers are unknown.
