US: Gunman holds hostage in Discovery Channel building

SILVER SPRING, Maryland — A gunman with what police described as "concerns" with the Discovery Channel networks took at least one person hostage in the company's suburban Washington headquarters Wednesday.
Montgomery County Police Capt. Paul Starks would not say if the man works for Discovery Communications now or worked there in the past. He also would not say whether anybody was hurt.
Montgomery County fire department spokesman Capt. Oscar Garcia said three bomb technicians responded to the scene and several more were on their way.
The initial report was of a suspicious package that was possibly explosive, said Garcia, who also said no one had been injured. He said some employees had left the building.
