Authorities said a woman and child escaped serious injuries in a single-vehicle wreck Friday night on Old Atlanta Road.

Both were taken to Northside Hospital-Forsyth for evaluation after the crash, which happened about 6 p.m. during heavy rain.

The rescue was complicated by the fact the vehicle had come to rest against a tree that had a limb touching a high voltage power line high overhead.

As bystanders attempted to free the woman and child, they could feel electricity but weren’t sure where it was coming from, according to authorities on the scene.  

Three sheriff’s deputies said they received minor electric shocks that didn’t require medical treatment.

Firefighters were able to quickly free the occupants, but authorities kept Old Atlanta closed until utility workers could remove the limb from the power line so the vehicle could be towed. 

It was not immediately clear what caused the crash. The Georgia State Patrol is handling the investigation.
