A fourth protester wanted by the NYPD in connection with the alleged assault of two cops on the Brooklyn Bridge a week ago after the Millions March has turned herself in. Cindy Gorn, 29, is charged with resisting arrest, obstructing governmental administration, and inciting a riot in the second degree, all misdemeanors.

The Post reports that Gorn, a resident of Prospect Park South who is a grad student at Columbia and has taught at Sarah Lawrence, entered the 5th Precinct with her attorney yesterday afternoon. The NYPD referred to her as "Female Suspect #2."

Maria Garcia, 36, Rob Murray, 43, and Zachary Campbell, 32, all turned themselves in to police over the past week since the incident, which left one NYPD Legal Affairs Lieutenant with a broken nose, and another with cuts and bruises.

Police claim that 29-year-old CUNY professor and Columbia grad student Eric Linsker was attempting to throw a trash can onto the Brooklyn Bridge roadway; when the two officers attempted to arrest him, other protesters intervened, and in the ensuing struggle, punched the officer and "de-arrested" Linsker, whose bag and jacket were left behind. Linsker, who teaches English, was arrested last Sunday.

The NYPD is currently offering a $25,000 reward for information regarding male suspects #1 and #2, a sizable sum considering that the department usually offers a maximum of $2,000 for information leading to the arrest of a "violent felon."
