People were forced from their Montgomery County apartments after a suspicious device and threatening note were found outside a new smoke shop.
Police evacuated four units above the American Royalty Cigar Shop near 1st Avenue and Fayette Street in Conshohocken shortly after 2 a.m. Wednesday.
A passing pedestrian said that he smelled gas and saw a handwritten note taped to front door of the cigar shop, which opened just over the weekend.
Police said a 40-ounce container was found in a backpack placed in the entrance way of the shop.
The bomb squad came in and deemed the device safe.
After a couple of hours, police gave the all clear and reopened Fayette Street.
No injuries were reported.
Detectives say it appears the threat was aimed at the store's owner, reported NBC10's Jesse Gary.
Conshohocken Police are running tests on the liquid contained inside the container, as part of a criminal investigation.
