A 22-year-old woman was sexually assaulted by a man in a city centre street in the early hours of Sunday morning.
Police are investigating and cordoned off part of Brightmoor Street, Hockley, where the attack happened, while forensic specialists examined the scene.
Brightmoor Street, on the south side of Hockley, between Goose Gate and Cranbrook Street, is a mixture of flats, shops and industrial units.
A Notts Police spokesman said: “Officers are investigating a report of a sexual assault of a 22-year-old woman by a man outside an address in Brightmoor Street, in the city centre, in the early hours of yesterday morning (Sunday 5 November).
“A cordon has been put in place at the scene and enquiries are ongoing. The woman is receiving specialist support.”
No arrests have been made and police are asking for anyone with information to get in touch.
Passerby Merryn Peachey, 20, said: “I was dropping some stuff off to a friend when I noticed what looked like a small police incident. At the time there was only a car and three officers that I saw, and a small amount of police tape.
“Later someone told me they’d seen black bags being moved into a car.”
Anyone with any information is asked to contact Notts Police on 101 or Crimestoppers anonymously on 0800 55111.
