Natural gas leak believed to be cause of Middletown apartment explosion

Baughman said the incident remains under investigation but criminal activity has been ruled out.

The explosion collapsed the roof of the apartment building that shot out debris into the parking lot.

One person was transported to Atrium Medical Center. At least two vehicles parked near the apartments received major damage from the flying debris.

Police said at least five of the six apartments were affected and those residents were assisted by the Butler County Red Cross.
