A group of five women and three men boarded the underground in Beijing and began drinking from a canister. Footage shows they wincing as they drink the liquid, that turned out to be some kind of poison.
Some then started collapsing on the ground while others in the group remained standing, but wincing in pain. The rest of the passengers fled in horror to the other end of the carriage.
The video then shows police entering the train at Tiananmen West Station. They dragged the victims onto the platform.
Four of the victims reportedly woke up later on while another four are seriously ill with poisoning. They were all victims of a stock exchange financial fraud.
