Witnesses of the multiple stabbing in Chengdu on Sunday night said the attacks were brutal.

After a bus on the No 42 route left a stop in downtown Chengdu at about 9 pm on Sunday, a middle-aged man took out a knife about 20 centimeters long and began stabbing passengers arbitrarily, footage from the bus camera showed.

The driver stopped the bus and opened both doors to allow passengers on board to flee. As the suspect fled, he also stabbed passersby.
