This was a funeral of a man who used nyaope. His friend apparently requested for nyaope instead of food at the funeral, hence the outcome.
Apparently this guys were causing havoc in the Bus traveling to the cemetery an the driver drove to police station an forced to get off an they went back to the funeral home to cause this chaos.

Another info: These nyaope users are protesting because their friend died and they believe he was killed by his parents because the postmortem confirmed traces of ratex or halephirimi. Funny enough those are said to be ingredients tsa nyaope.
