Tonight, Massachusetts Attorney General Martha Coakley announced the arrest of an Arlington man in connection with today’s discovery of numerous hoax devices in and around the city of Boston. Peter Berdovsky, age 27, is charged with placing a hoax device (Massachusetts General Laws, Chapter 266, Section 102A½), and disorderly conduct.According to authorities, at approximately 7:50 a.m. today, MBTA employees at the Sullivan Square station in Charlestown observed a suspicious device on a stanchion. They immediately contacted MBTA Transit Police, who responded to the scene. Additional law enforcement agencies, including the Boston Police Department, and the Massachusetts State Police, all responded and together commenced an investigation into the suspicious device. Throughout the day, additional devices were found at various locations in the city of Boston, as well as in Cambridge and Somerville.
