Delhi Chief Minister Arvind Kejriwal’s aide Bibhav Kumar was arrested Saturday in connection with the alleged assault on AAP MP Swati Maliwal, even as the party claimed she was “blackmailed” by the BJP as she faces a corruption case.

Kumar was picked up from the chief minister’s residence by a Delhi Police team, a senior police officer said, a day after Maliwal recorded her statement before a magistrate at the Tis Hazari court. “He will be produced before a court and police will seek his custody for further interrogation,” the officer told the media.
