Police: Suspect No.1: Season 4, Episode 6

4 - 6: Episode 6

Detectives hunt for a sexual predator after lone females walking in parkland in and around Hull are left traumatised after a man indecently exposes himself in broad daylight, with the only clue the distinctive red bike the man was riding. With the incidents increasing in frequency and more victims left disturbed, detectives mount a large-scale manhunt to find and arrest this dangerous individual before his behaviour escalates into physical sexual violence.
