Special CBI Judge Pradeep Chaddah dismissed the anticipatory bail plea of Dimple, who is Councillor of Sant Garh in west Delhi's Tilak Nagar.
The councillor's personal assistant Gagan Arora is also an accused in the case and was arrested by CBI on September 15.
The CBI registered a case against Dimple and his aide on the complaint of a builder that the councillor was demanding bribe of Rs 1.25 lakh to ensure that MCD's building department will not take action on the structure being constructed by him at Sant Garh area.
While dismissing his anticipatory bail, the court also noted that a complaint against Dimple has been filed before the Lokayukta by a businessman alleging harassment at the hands of the councillor.
The complaint before the Lokayukta was brought to the court's notice by the builder, who is the complainant in the bribery case.
