NAN reports that Sankara was allegedly arrested by Kano Hisbah in an uncompleted building with a married woman.
Şanlara denied the allegation in a statement he issued to newsmen on Thursday.
He claimed that the report of his arrest was a mischief aimed at tarnishing his established political carrier.
Meanwhile, the Director-General of Hisbah Commission in Kano, Abba Sufi, confirmed that Sankara will be arraigned in Court on Monday.
