WASHINGTON (WUSA9/AP) - After thorough on-scene investigation, officials have determined that no suspicious packages or letters were located at Joint Base Anacostia-Bolling in Washington, D.C.
Thomas Veale, DIA spokesman said, "Today, DIA's mail screening equipment alerted officials to the possible presence of a potentially harmful substance."
DIA has no further comment on this ongoing investigation.
Earlier today, U.S. officials said a package containing what authorities said could be ricin was found Tuesday morning at a military mail sorting facility at Joint Base Anacostia-Bolling in Washington, D.C.
A hazmat team entered the building at about 3:45 p.m. but have not yet determined what type of hazardous materials they are dealing with. Initial test indicate it may be ricin, a U.S. official told the Associate Press.
Senate Majority Leader Harry Reid, D-Nev., told reporters Tuesday there was an incident at the Bolling base that involved the "same substance" as recent letters sent to President Barack Obama and a U.S. senator.
The package was found at a Defense Intelligence Agency headquarters mail-sorting facility on the base, the U.S. official said.
The official was not authorized to speak publicly about the incident so requested anonymity.
