ATLANTA, April 8 (UPI) -- The Atlanta FBI says a suspicious package found in a restroom at Hartsfield-Jackson International Airport Wednesday appeared to be a military trip-flare.
The FBI said the package contained a "highly flammable substance," the Atlanta Journal-Constitution reported Thursday.
"This device could have caused very serious injury to anyone handling or tampering with this device," said the statement, released late Wednesday.
The device was rendered safe by the Atlanta Police Bomb Squad and taken away for examination by local and federal agents.
A part of the Atlanta airport's south terminal was evacuated, but operations at the airport were not significantly affected.
The FBI Joint Terrorism Task Force is investigating.
Authorities said the package was about the size of a chalkboard eraser and sat on a counter in the men's room.
