FBI Investigating Powder Letters Sent to US Congressional Candidate

The Federal Bureau of Investigation (FBI) said in a statement on Friday it is probing a series of suspicious letters filled with white powder that were sent to residences in the US state of Georgia, including the home of a Congressional candidate.

In addition, WAGA Fox 5 news station and WXIA 11Alive also received very similar letters containing suspicious white powder.

"On Thursday, June 15, 2017, a series of suspicious white powder letters were sent to Roswell, Georgia residents, one of which was the residence of US Congressional 6th District candidate Karen Handel," the statement said.

The FBI said more than a dozen letters were under review, noting the letters that were opened contained threats.

Nine letters were intercepted by the US Postal Service before they were delivered.

Initial testing found that the powder did not contain any known hazards, but additional tests will be conducted at the Georgia Department of Public Health as a precaution.
