The McMinn County Sheriff's Department is looking for a man accused of dumping sewage into the Hiwassee River.

A witness called police after spotting a man, later identified as Michael Calhoun, pumping sewage into the woods by the river, out of a septic truck.

The witness snapped a cell phone photo that spooked Calhoun and the woman he was with and they fled the scene.

The McMinn County Sheriff's Department has taken out a warrant for Calhoun's arrest.
