CCTV Released After Coventry Sex Assault
Detectives investigating a sexual assault on a Coventry woman have released CCTV images of potential witnesses they would like to speak to.
A 37-year-old woman was attacked on Moat Street car park just after 2am on Saturday 14 March.
It is believed the woman had left a nearby nightclub and was walking towards the car park with a man. She then walked under the underpass leading to Moat Street car park where it is believed she was sexually assaulted. The offender stole her handbag and fled the area.
Detective Phil Gwynne, from Coventry’s Public Protection Unit, said: "We really need the driver of the car in the image to come forward. We believe the driver of the car may have seen this woman walking towards the car park.
"The men in the images may also hold vital information that could help our investigation and we would urge them to contact me or one of the team at their earliest opportunity.
"In the image showing two men after looking at CCTV we believe the man on the right is black and the man on the left is white. CCTV shows they were in the area and they may have seen something, I am sure they will recognise themselves from the image and I would urge them to come forward.
"Officers continue to support the victim who has been left traumatised by her ordeal. I would like to reassure people in Coventry that this type of crime is extremely rare and that patrols have been increased in the area to offer reassurance.
"If you have seen anyone acting suspiciously in the area recently then we want to hear from you."
Anyone with information is urged to call West Midlands Police on 101.
