MANTECA (CBS13) — A now-former teacher for the Manteca Unified School District has been arrested on suspicion of inappropriate communication with a minor.

Manteca police say an incident allegedly involving Sierra High School teacher Jared Rio was reported to them by the school district back in July. Rio was put on administrative leave by the district as officials investigated the case.
