The Okhla MLA alleged that he was "being framed by the police" who is under pressure to arrest him.
However, senior police officials rubbished the charges.
"Police wants to arrest me in a false case. I requested them to not do so since I am personally involved in the ongoing fogging work in my area but they said that they are under pressure. I will be courting arrest at Jamia Nagar police station at 12 PM tomorrow," he said.
A case of sexual harassment was registered against Khan last week in southeast Delhi's Jamia Nagar Police station on a complaint by his sister-in-law.
A case under IPC sections 354(A)(sexual harassment), 506 (punishment for criminal intimidation), 509 (word, gesture or act intended to insult the modesty of a woman), 120B (punishment of criminal conspiracy) and 498A (husband or relative of husband of a woman subjecting her to cruelty) was registered against Amanatullah and the woman's husband.
