Witness appeal after sexual assault at park

Parts of a park in Nottinghamshire have been cordoned off by police investigating a sexual assault.
Officers said they were called to Sutton Lawn in Sutton-in-Ashfield at about 00:20 BST on Monday to reports a woman had been attacked.
Nottinghamshire Police said it was thought the "serious sexual assault" took place between 21:00 and 22:00 on Sunday and the victim was being supported by specialist officers.
Two areas of the park remain cordoned off and extra patrols have been put in place, the force added.
Witnesses have been urged to come forward.
Det Sgt Barry Haines said: "We know incidents like this cause great concern in our communities, and a team of detectives is working at pace on the investigation.
"It was a warm summer evening and we believe it was still light when the incident took place.
"We know there were people in the park at the time and believe they could have important information."
