Overview

• In late May, Gann ordered precursor chemicals online, tested explosive mixtures on Long Island on June 4, and then assembled at least seven improvised explosive devices in Manhattan.
• Prosecutors allege he stashed five devices and shotgun shells on SoHo rooftops before hurling one onto the Williamsburg Bridge subway tracks on June 4–5.
• No devices detonated and no one was harmed thanks to swift coordination among the FBI’s Joint Terrorism Task Force, the NYPD and the U.S. Attorney’s Office for the Southern District of New York.
• A federal grand jury returned the three-count indictment on July 22, more than six weeks after his June arrest in SoHo.
• He remains in federal custody pending trial as prosecutors warn the case highlights the ease of acquiring precursor chemicals online for destructive devices.
