I don’t know where the video is from. Could be Pakistan or an Arabic country.
The video is a CCTV footage from inside a building. It shows a security guard wearing a baseball hat sitting on a plastic chair. A few seconds into the video, he begins to twitch as if he was having a seizure.
A man passes by him, but pays no attention. The guard slumps back and his hands tense up with a twisting motion. He tenses up a few more times and eventually becomes lifeless, though in some moments he looks as though he’s performing agonal breathing.
Some guy then notices that the guard is unresponsive and makes a phone call. With the assistance from a few other men, they take the guard outside and into a rickshaw presumably to deliver him to a hospital.
According to the backinfo I got, the guard suffered a heart attack and died.
Props to Best Gore member @auggy-v1 for the video:
