Ah, I think it is the video I post above. It is the scene of assassination. The boss of the murderers who escape police's arrest later on posted an audio and a video on Facebook seeking the intervention from the Prime Minister.I cannot access to it now in my office, but it was the first one posted. IIRC, the title had the words, something like "... shot despite begging...". That was why it was painful to watch. And the culprit looks to have a darker complexion.
