Updated: Sheffield park sealed off after '˜serious sexual assault'

The victim is thought to have been attacked sometime between 22.35pm and 11pm as she was walking through Weston Park.

South Yorkshire Police has launched an investigation and the woman is being supported by specially trained officers.

The park, opposite the city's Children's Hospital on Western Bank, has been taped off and officers are guarding the entrances.

There is also an inner cordon in place close to the band stand inside the park.

Police cars and a police van are parked up at the scene.

Detective Inspector John Fitzgibbons said: “There is currently a large area of Weston Park cordoned off while we conduct initial enquiries at the scene.

“Additional police patrols will be provided over the coming days to provide reassurance and I would urge anyone who may have information on this incident to please come forward.”
