Looks like a French machine?
Curious what the pods on both sides are: Fuel, cargo or camera equipment?
He or she was flying too low over a residential area and kept coming around and around, at first we thought it was a police helicopter looking for something or someone but saw no markings. There is an N-number on the tail boom but not much contrast from the metallic light blue color of the craft.
The video is not great, sorry about that.
