Charges may soon be coming for a trio of New Athens High School students blamed for selling pills to their classmates, according to the St. Clair County State's Attorney's Office.

Police on Wednesday locked down the school and searched lockers. Investigators told the media that three 16-year-old students are believed to be trying to sell illegally possessed prescription pills to their classmates.

The boys were taken into custody by police but have been released to their parents while the case is under investigation.

School leaders received a tip Wednesday from a student about the alleged drug sales and called police.

Results of the investigation that followed have been shared with the State's Attorney's Office, according to New Athens police.
