Two minors and two adults were arrested after a masked 16-year-old in Kfar Kasra sprayed tear gas at another student his age, at the local high school on Wednesday.
The student ran away after the act, but police know his identity. Ten students in the classroom were mildly injured due to tear gas in the air.
Later on, a fight broke out between the two 17-year-olds and their parents. All four were arrested.
