OKLAHOMA CITY -

A third call about a suspicious white powder discovered on a letter has crews responding to the Oklahoma FBI headquarters, Thursday evening.

Investigators responded to the FBI HQ on 3301 W. Memorial Rd., shortly after 5 p.m. It was the third such call about a white, powdery substance discovered at a government building on Thursday.

Secret Service and FBI agents already responded to a scare involving a white, powdery substance at the U.S. Attorney's office downtown just after 2 p.m. At the time agents feared the white powder could be anthrax, but tests performed on the substance came back negative.
