I work at island police post (police coast guard stn). conducting final nightly patrol around 2am, towards ne of island (0.5km away from an education camp facility). came across mutilated wild boar body. radioed to stn to notify park authorities to clear the next day. i observe bright light above water body next to us beside road. fellow officer is unsure what it is, we determine it is drone (many drone enthusiasts visit here). attempt to look for the drone operator by walking towards nearby camp area. within 1-2mins, object then gets much brighter, pulsating lights. object is joined by 2 other emerging from unknown direction (they appear suddenly as if invisible then choosing to appear instantly). all this is very jarring. fellow officer spooked, unholsters revolver. i rush over to stop him from discharging revolver. objects accelerate suddenly and disappear. we are not sure of what occurred still.
