Noble County Sheriff Stephen Hannum says two juveniles are facing charges for throwing rocks from an overpass on to Interstate 77.
It happened last week around four p.m.
One car was damaged in the incident.
Hannum says the two juveniles-ages nine and 12-wandered from their home.
After the incident occurred, he says they were caught quickly. He says a deputy was patrolling the area, which has been on high alert during the past six-weeks.
Hannum says multiple throwing incidents have occurred but none have been connected. He says surveillance activity is now being used in the area.
