Possible sighting or drones

This could have been nothing or possibly drones, but I was looking over my balcony which faces roughly central and Indian School Rd.  There is a multi story building there.  I saw what at first from the distance were a few helicopters just hovering, or so I thought.  They had ref lights with a flashing Light underneath, moments later one zipped up and then to the right super quick, never seen any drone or aircraft move so quickly.  Then the other one zipped off to the other side and darted off behind the building.  I was concerned so I called phoenix pd to see if they had drones out and was advised they don't use drones.  Was very strange to see this because the lights On them we're so bright and have never seen anything move like that before most drones I have seen don't have lights bright enough to see 1/4 mile away
