COLUMBUS, Ohio - Explosions rocked downtown Columbus and flames shot from manholes overnight.
Now, WBNS reports that AEP may have pinpointed a cause. The company blames an explosion in an underground vault that stores electrical equipment and powers transformers.
At least three blasts, apparently underground, occurred in the early hours of Friday morning.
Police cordoned off streets, and the electric company cut power to several surrounding buildings. Some traffic lights were knocked out. Smoke was seen coming from one of the manholes.
The investigation was continuing. No injuries were reported.
