The disturbing CCTV clip reveals as the unidentified man strolled aimlessly around Leeds city centre shortly before he found his 24-year-old female victim at around 5am on Friday 14 August, 2015.
The Police believe he was looking for someone to attack when he targeted the young woman. The victim was on her way to get a taxi home after a night out when the assailant approached in the Kirkgate area of the city.
It was clear that he said something as he walked alongside her before he picked her up (pictured) and carried her to the scene of the attack.
Grain photo of the attacker was released to the public incase anyone can recognise him. Photo below:
