A 22-year-old armed man who took a hostage at random in a Pittsburgh office building today has surrendered peacefully after a six-hour standoff, police say.
The gunman, identified as Michael Thaxton, was handcuffed and taken from the scene in a police van.
The hostage was freed unharmed, the Associated Press reports.
Police Chief Nate Harper said earlier that no explosives were found in the 16th-floor offices of the CW Breitsman investment company at Three Gateway Center as they initially feared.
Before authorities shut down his access to his Facebook page, Thaxton communicated with friends who tried to get him to end the ordeal. His mother also came to the scene and spoke with him by phone, police say.
Early in the standoff, which began at 8:10 am. ET, Thaxton posted this message on his Facebook page: "i cant take it no more im done bro"
