Interference, Inc., hired two people to distribute twenty devices throughout Philadelphia on January 11. One of these was Ryan, a 24-year-old from Fishtown, who claimed that he was promised $300 for installing the devices, only 18 of which were actually functional. Following the scare in Boston, the Philadelphia Police Department recovered three of the 18 devices. Joe Grace, spokesman for Philadelphia Mayor John F. Street, said, "We think it was a stupid, regrettable, irresponsible stunt by Turner. We do not take kindly to it." A cease-and-desist letter was sent to Turner, threatening fines for violating zoning codes.
