Several Bharatiya Janata Party leaders, including Subramanian Swamy, on Monday joined party MP Mahesh Girri, who has been staging a hunger strike outside Delhi Chief Minister Arvind Kejriwal’s house since Sunday to protest against Kejriwal allegedly accusing of him being involved in the murder of a civic body official.

Girri told NDTV he would not end his protest until Kejriwal came out and apologised. Meanwhile, Kejriwal took to Twitter, where #BaharAaoKejriwal was trending, to demand Girri’s arrest.

MM Khan, an estate officer, was shot dead in Jamia Nagar on May 16, a day before he was to give an order on the terms of the lease a four-star hotel. The hotel was on a property leased out by the civic body. The hotel's owner Ramesh Kakkar and six others were arrested.

The Aam Aadmi Party then alleged that Girri had links with Kakkar. Kejriwal said it was Girri who had forwarded Kakkar’s letter, which was addressed to Lieutenant Governor Najeeb Jung asking him to sack Khan. The party also suspected Vice Chairman of the civic body Karan Singh Tanwar of playing a role in the murder.

Kejriwal had then written to Lieutenant Governor Jung, saying Girri and Tanwar had threatened Khan with dire consequences a few days before his murder. The Delhi Police said they do not have any evidence against Girri or Tanwar yet.
