Boomarang like shaped with five lights made a speed big heart like path and suddenly distriduted and vanished

I was with my brother for a walk on the street just then I saw a plane like object with three differing lights advancing upare in the sky with a great speed . I considered it to be a aeroplane as usual. But suddenly the speed increased to an extreme and it flewed for a few seconds behind a tree (was out of sight ) and suddenly I saw it loosing altitude comming just above us forming a C like cure from the starting . I just looked above and by my estimation it was 650 meters just above my head . I saw two whitish coloured boomarang like discs facing opposite to each other and were joined by a strip of bwonish colour. I saw almost five lights on it ( still I distinguished and remembered four) get were - red yellow brown and green . Then it just flew of my head in another C curve with a sudden great speed advancing up in the sky. Now I saw it releasing one of its light , then it realeasd tow of its lights . Now it created a circular movement and all five lights ! were seperated and two went towards the east one towards north one towards north- west and one towards south
