A case of sexual harassment was registered against Khan last week in south-east Delhi's Jamia Nagar Police station on a complaint by his sister-in-law.

Delhi Police on Saturday had lodged an FIR against Khan claiming that he pressurised his sister-in-law for establishing a physical relationship.

"Khan is booked under Section 354 (assault or criminal force to woman with intent to outrage her modesty), Section 509 (word, gesture or act intended to insult the modesty of a woman) Section 506 (criminal intimidation) Section 498 A (relative of husband of a woman subjecting her to cruelty) and criminal conspiracy," a senior police officer told reporters.

Earlier, the Okhla MLA held a press conference at the AAP office and denied the charges. He added that he was having "no connection with the woman at all". Following a complaint by the woman, an FIR was lodged against Khan at the Jamia Nagar police station in south Delhi.

The AAP legislator earlier wrote a letter to Delhi Chief Minister Arvind Kejriwal and resigned from all government posts, saying that he was "tired" of giving "clarifications" on various allegations levelled against him.

In his letter to the Chief Minister, Khan wrote that he served Delhi people with full dedication since the day he was elected. "I exposed several corruptions of the previous government after I became the chairman of Delhi Waqf Board. But some people are not liking my honesty and spirit of service as they are framing me and my family in fake cases," Khan said in the letter.
