New Delhi: Stepping up its attack on the Arvind Kejriwal-led Aam Aadmi Party (AAP), the BJP on Friday said that Delhi's ruling party is only good at holding press conferences and that they must start 'comedy shows' to entertain people.

Delhi BJP leader Vijendra Gupta said, “"Since the time their name popped up in the water tanker scam's FIR, they are baffled and behaving wildly. They are trying to divert people's attention in between a murder and a letter. They only hold press conference, they can only mislead and confuse people and their credibility is zero. People laugh at them and people listen to them as a mere entertainment, they must start comedy shows and come every day on TV with something new and entertain people."

"After Delhi Police gave clean chit to Maheish Girri, the case is solved. If you have any doubts, then you should go to court, or file a report in the police station rather than coming on television debates," Gupta was quoted as saying by the ANI.

BJP had earlier called AAP a 'drama company' and dubbed Kejriwal as a 'dramebaaz' for their stand on Lokpal and other issues of utmost concern.

As the controversy rages over the murder of NDMC legal adviser MM Khan, the Delhi Police had yesterday claimed it is conducting an impartial probe into the matter and gave clean chit to BJP MP Maheish Girri and NDMC vice-chairman Kanwar Singh Tanwar.

AAP had earlier alleged that Lieutenant-Governor Najeeb Jung's role in the Khan case was 'suspicious' and demanded he be arrested.

Union Minister of State for Home Kiren Rijiju said the Delhi Police is investigating the Khan murder and is making "good progress."

Rijiju's comments come after Kejriwal accused BJP MP Maheish Girri of being allegedly involved in the Khan murder.
