An unknown issue at a local oil and gas well site prompted local authorities to evacuate several homes near Oil City Friday evening.
Carter County Emergency Management Director Paul Tucker said 20-30 homes were evacuated as a precaution after a natural gas leak was reported at a rural well site in northwestern Carter County.
Tucker said the cause for the leak is still unknown and the extent and volume of gas leaked had not been reported.
Evacuated residents were allowed to return home early Saturday morning.
