Tanko, who previously admitted to conspiracy, denied the remaining three charges against him, including kidnap and subsequent killing of the young girl.
Kano State Magistrate Court 12 sitting at Gidan Murtala has ordered the remand of the suspected kidnappers and killers of five-year-old Hanifa Abubakar.
Abdullahi Ganduje, governor of Kano, says he will sign the death warrant immediately if the suspect arrested over the killing of Hanifa Abubakar is sentenced.
