The Clerk was manning the front desk of Weatherfield Police Station when Tony Gordon walked in to hand himself in. Standing in soaking wet clothes after dragging Roy Cropper out of the canal following their altercation, Tony calmly stated that he'd come to confess to the murder of Liam Connor.
The officer called for DC Coogan who then led Tony to the custody suite to change out of his wet clothes and informed his superior, DS Smith about the development.
