Bombs Detonated in Park After Storage-Unit Seizure

A series of explosions shook houses Thursday night as authorities destroyed pipe bombs in East Whiteland's Valley Creek Park.

Two bomb-disposal units were among the multiple emergency response teams working at the Public Storage facility in Frazer Thursday evening after a large amount of explosives was found inside a storage locker.

FBI agents and bomb technicians worked in and around the building, located on the unit block of Lancaster Avenue, as local police and fire departments controlled traffic, maintained a perimeter and kept ready to respond to any incidents.

Around 8:30 p.m., bomb squads from Montgomery County and Philadelphia began hauling the explosives from the storage facility to nearby Valley Creek Park. The explosives were transported inside large metal containers on trailers, and each trip involved a convoy of fire engines, ambulances and police vehicles.

Dave Harman, who lives with his family in a house on the park grounds, said FBI agents told him they had discovered a storage unit full of pipe bombs and planned to detonate them in the park. He and his family were told to keep away from windows during the explosions.

Earth-moving equipment was present in the park, and multiple people at the scene said the bombs would be buried before being detonated.

Shortly after 11:15 p.m., as a light snow fell, the first in a series of explosions shook houses and woke sleeping residents miles away. At least five explosions occurred before they stopped around 1:15 a.m. Friday.

There were also reports of an explosion earlier in the day, around 7 p.m., but employees at businesses near Public Storage said they did not hear anything at that time. 

The FBI had notified East Whiteland Police that they planned to execute a warrant within the township, but the circumstances that led the agency to Malvern are unclear. The Daily Local News reports that the storage locker was registered to Istvan Merchanthaler, a 42-year-old man facing federal charges related to a $2 million Ponzi scheme. Harman said agents told him a Maryland resident had been arrested in connection with the bombs. 

Among the emergency responders present at the storage facility and the park were East Whiteland Police, East Whiteland and Malvern fire and ambulance companies, East Whiteland Fire Marshall, Goshen Fire Company and the Montgomery County Sheriff's Department. Several people at the two scenes said agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives were also involved, but that could not be confirmed.
