JACKSONVILLE, Fla. -- The Jacksonville Sheriff's Office and a Hazmat team from the Jacksonville Fire and Rescue Department is investigating a suspicious package that contained a white powdery substance when detonated.

At 8:30 a.m. Tuesday, someone called JSO about a suspicious package, which was wrapped completely in duct tape. The bomb squad was on scene at the 400 block of North Hogan Street.

A bomb squad robot "made it safe" by setting the package off with an explosive cap. The white powder is not lethal, but because it is not yet certain what it is, JSO is keeping a wide perimeter, said Public Information Officer Melissa Bujeda.

City Hall did not have to be evacuated, said spokesman David DeCamp. However, people on the south side of the building were asked to stay away from the windows during the detonation.

Business at City Hall is still going on as usual. People will just need to use the back door, DeCamp said.

Other businesses in the area have been made aware of what is going on, Bujeda said, and will be able to decide if they want to evacuate or not.

During the investigation, several streets were blocked but opened around 2 p.m. This included Hogan Street from Monroe Street to Duval Street and Laura Street from Adams Street to Duval Street. The JTA Skyway Express was also shut down temporarily.
