The explosive device, which police believe was a commercial-grade firework, was detonated and destroyed the mailbox sometime between 7 p.m. Tuesday and 9 a.m. Wednesday, Butler Township Police Chief John Porter said in a media release.

Police did not say what road the incident occurred on but described the area as a rural part of the township. 

“Since tampering with a mailbox is covered under federal law, federal authorities have been notified and are participating with us in a joint investigation,” Porter said. “Our initial investigation shows there is no indication of any type of hate or bias crime at this time.” 

Authorities continue to investigate.
