Three students from a Keystone Charter School in Mercer County are in trouble after police say they were caught with THC vape pens.

Three students were charged last week in separate incidents at the school on Good Hope Road in West Salem Township.

According to State Police, a 14-year-old Greenville boy had a THC dab pen at the school, which provides educational alternatives for students who have difficulty functioning in traditional public schools.

Later that afternoon, police say two 15-year-old girls, one from Greenville and one from Sharon, were caught in class passing a dab pen to each other.

The three face charges in Mercer Juvenile Court.
