According to the complaint, Mr Khan had used the word during the promotion of his film 'Tiger Zinda Hai'.
The plea, filed before Additional Sessions Judge Sidharth Sharma, alleged that the accused persons had "committed atrocity" on the members of the caste and insulted and humiliated them by making the casteist remark.
The court put up the matter for consideration on February 27 and sought a reply from the Station House Officer concerned on the complaint.
Mr Singh said he had in December last year filed a complaint at a police station, but no FIR has been registered yet, due to which he filed the application before the court.
