A defamation notice has been reportedly sent to Sidhartha Mallya, director of the IPL franchise Royal Challengers Bangalore, for his remarks on micro-blogging site Twitter in the molestation case involving one of his players Luke Pomersbach. Zohal Hameed, the US national who has alleged that Mr Pomersbach molested her at a five-star hotel in Delhi on Thursday night, has also reportedly lodged a complaint with the Delhi commission for women against Mr Mallya for his tweets on the incident.
