In total, ten cities were involved in the marketing campaign, which began two to three weeks before the incident. The NYPD contacted Interference, Inc., to request a list of 41 locations where the devices were installed. Officers were able to locate and remove only two devices, both located near 33rd Street and West Side Highway at the High Line overpass. The NYPD did not receive any complaints about the devices, according to police spokesman Paul Brown. At 9:30 p.m. on the evening of January 31, the Chicago Police Department received a list of installation locations from Interference, Inc. Police recovered and disposed of 20 of the 35 devices. Police Superintendent Philip Cline admonished those responsible for the campaign, stating, "one of the devices could have easily been mistaken for a bomb and set off enough panic to alarm the entire city". Cline went on to say that, on February 1, he asked Turner Broadcasting to reimburse the city for funds spent on locating and disposing of the devices. Two men were briefly held in connection to the incident.
