Mumbai: A senior public prosecutor (PP), who was representating Municipal Corporation of Greater Mumbai in many legal cases in sessions court, has been arrested by the Anti-Corruption Bureau (ACB) Mumbai officials on Thursday while accepting Rs 1 lakh bribe from a builder in exchange of not arguing against him in the court in a legal case. The builder had recorded the PP’s bribe demand using a spy pen camera and later used it to nail her, ACB sources told Mid-Day.
