Pittsburgh police responded to a report that a box labeled "pressure cooker" with a Massachusetts return address was delivered to a city office building — only to find it really was a pressure cooker, ordered by an employee.
Police Lt. Shirley Sloan said the police response Wednesday was born out of an abundance of caution in the wake of the Boston Marathon bombings.
"It was really tense there for a while," Sloan said.
The FBI has said Monday's blasts were caused by homemade bombs crafted using pressure cookers.
Pittsburgh Police received an employee's report about the package being delivered just before noon.
By the time the city bomb squad arrived, Sloan says another employee of a company that recently moved into the building had claimed the package.
