A metallic box containing ammunition was dropped from a military helicopter Wednesday night during a training exercise in Northwest Miami-Dade, according to the Miami-Dade Police Department.
Police ask that anyone who sees the box to leave it alone and call 911 immediately.
Earlier this week, Miami-Dade police announced that there would be a joint military training exercise in Miami-Dade and Broward County, but did not specify times or locations of the training.
The routine training helps military personnel operate in urban environments, prepare forces for upcoming deployments and meet mandatory training certification requirements.
It was not clear exactly when or where the box fell.
