Nottingham sex attack witness image released
Images of a man sought in connection with a serious sexual assault in Nottingham have been released.
A 20-year-old woman was dragged into an alleyway on Malin Hill, near High Pavement, in the early hours of 5 June.
The man, described as white, aged between 20 and 45, and of large build, was seen on CCTV in the area at the time.
Police said extra patrols had been put on but advised women not to walk alone in the area at night.
Officers added people should stay in well-lit areas with their friends, and those who intended to go out should ensure they knew how they were getting home.
Det Chf Insp Simon Alexander said: "We have clear images of a man in the area around the time of the attack. We are keen to speak to him and we hope that someone out there will know who he is.
"The man may even recognise himself in the clip, and I would urge him to please either call police or visit his nearest police station so that we can speak to him."
