RAPID CITY, S.D. — A Rapid City man has been arrested following an investigation into an explosive device located on the porch of a MacArthur Street residence.

Police were dispatched to a house on the 100 block of MacArthur Street on August 9 at around 5:20 p.m. for a report of an incendiary device that was located on the porch of the residence.

On arrival, police made contact with the occupant of the residence, and they located the explosive/incendiary device and reviewed security footage from a neighboring residence.

During the course of the ensuing investigation, detectives learned of a similar incendiary device which was located at a residence north of Rapid City in Meade County.

By examining common contacts between the two incidents, police identified 50-year-old George Irwin-Schacht of Rapid City as a person-of-interest in the case.

A search warrant was requested and granted for Irwin-Schacht’s residence, and police located additional bomb-making materials at his home.

Irwin-Schacht was brought to the RCPD’s Criminal Investigations Division for an interview regarding the two incidents. Following the interview, Irwin-Schacht was placed under arrest for Placement of an Explosive Device to Endanger Human Life and Possession of Explosives with intent to Injure, Intimidate, or Destroy Property, both felony offenses.

He was subsequently transported to the Pennington County Jail.
