Indianapolis, IN – IFD and IMPD investigators say a gas line opening was to blame for the explosion at a west side apartment complex.

Investigators say an unintentional, accidental opening of a gas line inside the townhouse of origin caused the explosion at the Pangea Riverside Apartments on May 15.”The slow release of this natural gas into the townhome interior continued over a period of time long enough to reach a point of saturation that caused an explosion.. at the point when the correct mix of oxygen and an ignition source was introduced to the gas rich environment.”

Six people were injured in the explosion, though none suffered life-threatening injuries.Many residents were displaced because of the explosion.

IFD and IMPD say the investigation is complete.
