State Police are investigating a bomb threat at the Department of Environmental Conservation office in Rotterdam.

The threat was sent by email Wednesday morning, investigators said.

A search of the location found no explosive devices, according to investigators.

DEC offices across the state have reported bomb threats following the death of popular squirrel, Peanut, who was seized by the agency and euthanized.

At least 10 bomb threats were reported statewide on Wednesday alone.

The investigation into the source of this threat is ongoing.
