ZURICH, SWITZERLAND (AP) -- A high-tech, but commonly-used, tool has helped Swiss police bring down some suspected marijuana farmers.

Officers stumbled across a large marijuana plantation while using Google Earth.

They discovered the plantation while investigating an alleged drug ring.

Investigators say they were using the satellite mapping software to locate the address of two farmers suspected in the drug operation -- when they spotted the two-acre illegal crop hidden inside a corn field.

Police arrested 16 people and seized more than one ton of marijuana.
