A man in his 50s attacked two passengers who asked him to wear a mask on a line no.2 subway train during morning commute.
The man got angry when he was asked to put on a mask and began slapping the passenger on the face multiple times with his slipper.
Another passenger sitting nearby was also assaulted and verbally abused by the man who attempted to strangle him.
A total of 349 people have been arrested for face mask-related conflicts over the last three months since May 26 when the government applied a "No mask, no ride" policy on all public transportation.
Among them, 164 people were held for assault.
