Javed Khan, former councillor of Gaya Municipality, against whom an arrest warrant issued by a Gaya court was pending since December, presided over the election meeting of Kumar here yesterday.
The warrant was issued in connection with the murder of a property dealer Naushad Khan in April last year.
After the rally, when a hue and cry was raised about a fugitive sharing dais with the CM, the police came into action and arrested him later in the evening.
The incident provided the opposition an opportunity to target the ruling party.
Senior BJP leader and party candidate from Nawada Giriraj Singh said it raises a question mark on the law and order situation in the state.
Senior minister Vijay Chaudhary, however, defended the government saying the moment the incident came to light he was arrested and sen to jail which shows the government's commitment to deal promptly with lawbreakers.
