Not sure exactly where this is from but it appears to be South East Asia. CCTV picks up the electrocution of at least three people as they are all walking through a flooded street. One man with his motorcycle appears to be killed instantly. We see a bright flash before he falls over with his bike. Others appear to be hit and shocked but manage to run away. No definitive answer as to what happened, but it seems likely a power line fell. Incident occurs early in the video, the rest is just the after effects of people dealing with it.
Bad ass props to RGM member @bannedanna for this shocking entry.
