HUMMELSTOWN, Pa. — South Hanover Township's municipality building is closed until further notice after a disgruntled resident allegedly sent an envelope to the office containing an unidentified white powder at 161 Patriot Way, township officials said.

Authorities arrested a man immediately following the report who allegedly resisted code violations for three weeks leading up to the incident.

Lynn Wuestner, the South Hanover Township manager, said neighbors had complained about the man having trash and a porta potty on his front lawn.

“The place where he’s living some deem to be uninhabitable—there’s no water, sewer, or electric," said Wuestner.

At this time, township officials have not yet identified the man charged in connection of the incident, citing safety.

According to court documents found by FOX43, a South Hanover man by the name of George Samuel Tregea was cited for charges similar to those mentioned by sources. Court documents state that Tregea was charged with two counts of harassment after repetitively contacting the township building at inconvenient hours

Township officials told FOX43 that when the township notified Tregea of the violations, he started leaving vulgar late-night voicemails to the township.

The resident then allegedly mailed the letter full of white powder to the township on Monday, Sept. 15.

“We’ve actually been living in fear; it was a very fearful situation," said Wuestner. “You hear about that in other areas of the country and you never think that that’s going to happen to you.”

Residents who need to access the building are told to call the main office's number at 717-566-0224 to access the building.

In a statement on Facebook, the office said that there is no current threat to the public, and that all meetings and events are scheduled as planned.

The township also stated that the facility will remain closed until the investigation is complete in order to preserve the safety of their staff.

Pennsylvania State Police charged a suspect on Friday, but following the events of this morning, the Board of Supervisors decided to lock down the township building.

Pennsylvania State Police are currently investigating the scene, and updates will be made as more details become available.
