'Explosion Noises' Heard In Upper Merion Posed No Danger: Police

UPPER MERION, PA — Police said that the explosions that were heard by residents in parts of Upper Merion Township on Monday posed no danger, and originated from outside of the township.

The exact nature of the explosion noises is still unclear. But Upper Merion Police Chief Thomas Nolan told Patch that they were part of a police training exercise nearby in Tredyffrin and Radnor townships.

Tredyffrin Township notified local residents about the training earlier Monday.

"There is no threat to the community but an increased law enforcement presence, including a helicopter, may be observed," Tredyffrin police shared in their statement.

The noises were reported during the afternoon Monday on Croton Road, Upper Gulph Road, King of Prussia Road, and surrounding neighboods in Upper Merion's Wayne section.

Police said the exercises and any related explosion sounds were never a threat to the public.
