In a peculiar turn of events, the Manhattan District Attorney’s Office has issued a subpoena for a parody Twitter account in relation to the July incident that saw white flags placed on top of the Brooklyn Bridge. According to The New York Times, the subpoena was issued to the @BicycleLobby Twitter account on Friday, a move intended to reveal the identity of the person or persons behind the posts. The subpoena’s existence seems to indicate that investigators believe those behind the account could potentially be helpful in determining who placed the flags on the bridge.
