On April 20, 1995, a powerful pipe bomb exploded beneath a wooden wheelchair ramp on the north side of Province House, destroying glass in windows and causing some minor structural damage. Several passersby were injured and the explosion occurred only five minutes after an entire class of school children on a tour of the building had passed through the area. The bombing occurred only one day after the Oklahoma City bombing and is considered to be a copycat action. Responsibility was claimed by a group calling itself Loki 7; however, a subsequent police investigation and criminal court case blamed a single individual, Roger Charles Bell.
