Go to balai & make a police report & tell your next door neighbours to help spread to the rest of the community.

WhatsApp the video to your neighbours so they can forward it to the rest.

Also like ktards said, make sure your house security is beef up & make sure living room & outside house lights.are.on.

Just do.your civic.duty by reporting to police.& informing.next.door.neighbours.
There is a limit to how.much you can do as a normal citizen.

Whether police will take action even with all evidence is beyond your power & you should not get too worry over it.

Stay safe & Selamat Hari Raya in advance.
