Mumbai, Feb. 7 -- Former Mumbai police commissioner Param Bir Singh was on Thursday removed as the executive director of the Lilavati Hospital and Research Centre in Bandra, hours after he filed a criminal complaint against its trustees, including Prashant Mehta and Rajiv Mehta. The trustees rejected the allegations, with Prashant Mehta calling them "totally bogus and motivated", and said they had filed a counter-complaint against Singh. In his complaint, Singh flagged certain malpractices in the operations of the Lilavati Kirtilal Mehta Medical Trust (LKMMT), which runs the hospital. The complaint includes allegations of forgery, misappropriation of trust funds, criminal intimidation and other offences. Singh also informed the trust's chairperson, Charu Mehta, about the alleged malpractices via email on February 2. He filed the complaint after the LKMMT Board or Charu Mehta did not act on his concerns, sources added. Charu Mehta is the mother of permanent trustees Rajiv, Rajesh and Prashant Mehta. "I did what was in the charter of my duties," Singh told HT. "I have nothing to fear. I will challenge my removal before the appropriate forum." Prashant Mehta dismissed Singh's allegations: "On the contrary, we have filed [a police complaint] against him and Rajesh Mehta for forgery and defalcation." He alleged that Singh and Rajesh Mehta had forged the minutes of a board meeting. Rajesh Mehta did not respond to calls or messages. Rajiv Mehta said Singh's complaint is "bogus, unprofound and lacks any legal merit"....
