Parking Authority employee Susan Wojtkowski pleaded not guilty in Central Judicial Processing court today to a charge of obstructing a governmental function. The matter was referred back to Bayonne Municipal Court with a court date of Jan. 8.

Police said that on Dec. 7, Wojtkowski stood in front of an unmarked police car and prevented two plainclothes detectives, who had already identified themselves, from pursuing a drug suspect until she could affix a ticket to their windshield.
