Did you hear those loud booms across Downtown Buffalo?
7 Eyewitness News has learned that they are from an FBI training scenario taking place at the vacant Shoreline Apartments on Niagara Street on Wednesday.
On Thursday, some eagle-eyed residents noticed a black helicopter that hovered over the city before landing on top of the One Seneca Tower.
A spokesperson for the FBI tells us the public is not in any danger and all of these activities are part of a large training exercise.
The training runs from Tuesday to Thursday.
