On January 31, 2007, at 8:05 a.m., a passenger spotted one of the devices on a stanchion that supports an elevated section of Interstate 93 (I-93), above Sullivan Station and told a policeman with the Massachusetts Bay Transportation Authority (MBTA) of its presence. At 9 a.m., the Boston Police Department bomb squad received a phone call from the MBTA requesting assistance in identifying the device. Authorities responded with what the "Boston Globe" described as "army of emergency vehicles" at the scene, including police cruisers, fire trucks, ambulances, and the Boston Police Department bomb squad. Also present were live TV crews, a large crowd of onlookers, and helicopters circling overhead. Peter Berdovsky, who had placed the device, went to the scene and video recorded the situation. He recognized the device under police investigation, but made no attempt to inform them. He returned to his apartment and contacted Interference, the company who had hired him to place the lights. Interference told him that they would handle informing the police and that he should personally say nothing about the situation.
