Deadly Ohio Bank Explosion Caused by Mistakenly Cut Gas Line

Investigators reveal workers cut a pressurized gas line, leading to a fatal blast in Youngstown.

The explosion killed a bank employee and injured several others, including one critically.
The blast occurred six minutes after workers cut the gas line, thinking it was deactivated.
The explosion blew out the ground floor of the Realty Tower, sending debris across the street.
Workers triggered the fire alarm and evacuated the building upon realizing the gas line was pressurized.
Authorities are investigating why the gas line was still pressurized during the construction work.
