Two university professors were indicted for their roles in an attack on cops during an anti-police demonstration on the Brooklyn Bridge, Manhattan prosecutors said in court Tuesday.

Barnard professor Cindy Gorn, 29, and Rutgers University instructor Zachary Campbell, 32, were initially arrested on resisting-arrest and obstructing-governmental administration charges for the Dec. 13 melee.

But the charges in the indictment are still sealed.

Gorn and Campbell were busted for preventing police from arresting protester and fellow academic Eric Linsker.
