Police in north suburban Lincolnshire launched a drug investigation at Stevenson High School that was unraveled through text messages.

So far, one student has been arrested. Others have been suspended.

Investigators confiscated cellphones that revealed a drug-trafficking operation at the school. Police explain the primary drug at the center of the probe is marijuana, but it may expand to include others.

The investigation reportedly began last fall with an incident involving one student and it developed into something much larger.
