The Internal Revenue Service office on East Main Street in Riverhead was evacuated Wednesday morning after a “suspicious package” was left outside the building, Riverhead Town Police said.
A security officer inside the building called police after finding a suitcase under an air conditioner behind the building about 8:30 a.m. The building was evacuated as authorities investigated.
The Suffolk County Police bomb squad responded and an X-ray found that the case contained an electronic device. A robot was used to open it and found clothing and “harmless items” inside, authorities said.
