Incheon police on Friday are investigating two men believed to have sprayed four elementary and middle school students with a fire extinguisher, allegedly because the children were smoking.

According to the Incheon Nonhyeon Police Station, the students reported that one man sprayed them while the other man filmed the incident in the staircase of a Nonhyeong-dong, Incheon, shopping center at around 4:56 p.m. on Thursday.

It was reported that the two men were employees at the shopping center. They told police that they acted in such a way because of the smoke being emitted from the cigarettes the students were supposedly smoking.

The two men have not been taken into custody, and officials are analyzing the surveillance footage to see if the man sprayed the fire extinguisher directly at the children.
