1 light came from the south, hovered ,split into 2 new lights , series of maneuvers , remerged with the original light and sped off

a bright point of light came from the south as i was driving home from cadets ,it appeared to move too swiftly for a helicopter or light aircraft. It stopped overhead at about 1000 feet approx, 2 more lights detached themselves from the original lightand began to circle it. This made it clear that it was in no way a normal object, as the 2 lights stayed precisely opposite to each other as they rotated around. The 2 lights performed what i could only describe as an infinity symbol like maneuver before merging again with the original and taking off at very high speed on a reciprocal course (to the south) The lights were all white with no indication of beacons etc as per an aircraft. I turned off my engine the whole time the three lights were seperated and could hear nothing ,much less a helicopter hovering none to far overhead! the lights all moved swiftly and smoothly There wasnt a cloud in the sky and i could plainly see the stars near to the horizon.
