DETROIT, March 19 (UPI) -- The FBI says it is trying to determine if a suspicious package left near the McNamara Federal Building -- home of the FBI -- in Detroit was a bomb.
The Detroit Bomb Squad detonated the package on Belle Isle Friday and FBI agents were trying to determine its contents, The Detroit News reported Saturday.
FBI Special Agent Sandra Berchtold stopped short of saying the package was a bomb, but said "explosive components" were found … the investigation is ongoing."
The device was discovered in a dumpster near the federal building, prompting police to close the area. A bomb squad officer wearing protective clothing removed the metal box.
It was the second suspicious package found in Detroit this week.
"We've been busy," said Detroit Police Inspector Don Johnson.
The high rise in downtown Detroit also houses offices of the Internal Revenue Service, the U.S. Army Corps of Engineers, the Social Security Administration and other government agencies.
