New Delhi: Aam Aadmi Party (AAP) on Sunday refused to accept the resignation of its legislator Amanatullah Khan and slammed the "Modi Police" for registering an FIR against Khan who they said was being "framed" for exposing corruption in the Delhi Waqf Board.

On Saturday an FIR was registered against Khan at the Jamia Nagar police station over molestation charges levelled by his sister-in-law.

"We refused to accept his (Khan's) resignation. It's a six-year-old family matter and his in-laws are dragging him into it," Delhi Deputy Chief Minister Manish Sisodia told reporters at a press conference here at the AAP office.

"We have found out in our investigation that he is being dragged into it," he added.

On Saturday, Delhi Police booked Khan under 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) of Indian Penal Code (IPC).

Sisodia said that Khan was being framed in this case for exposing corruption in the Waqf Board and he has nothing to do with his brother-in-law's wife for last four years.

MLA from Okhla, Khan, who was made the Chairman of Delhi Waqf Board in March, was recently accused of involvement in an alleged recruitment scam there and the Anti-Corruption Branch (ACB) launched a "preliminary inquiry" against him.

Khan on Saturday claimed to have raised financial irregularities of Rs 280 crore in the Waqf Board.

Terming Delhi Police as "Modi Police", Sisodia said "Modi Police has set a scanner against AAP. As soon as any complaint is made, the Delhi Police register it without making any inquiry."

Sisodia made allegation against Prime Minister Narendra Modi and BJP President Amit Shah asking why they are not being probed even after an IAS officer (Pradeep Kumar), now suspended, had already moved a notice in the Supreme Court for the CBI to probe some tapes which allegedly showed them as using Gujarat police to conduct surveillance on a woman.

Terming the issue as "India's Monica Lewinsky case", Sisodia challenged media to start a debate on the issue.

He said the AAP party knows "how to clean itself", and it does not care for the allegations of the "Modi government or Modi Police".

"Our boss is not Modi. Our boss is janata (citizens) who knows everything. We are doing our work," he added.
