Officers and other emergency services at several locations are dealing with an "ongoing serious incident", according to Nottinghamshire police.

The Nottingham Express Transit (NET) tram network also said it has suspended all services due to "major police incidents around the city and suburbs".

Emergency services are present at areas including the Maid Marian Way junction of Upper Parliament Street.

Other roads cordoned off include Ilkeston Road, Milton Street, Maples Street, and Woodborough Road, from the junction with Magdala Road into the city.

A statement from the police said: "There are multiple road closures in place throughout the city while the incident is being investigated.

"We are asking the public and motorists to please avoid the following areas and plan alternate routes."

Police have not confirmed what the incident is involving, but Twitter user Robbie Paul-Stone wrote someone was "being treated on the side of the road".

"I didn't see any cars. It's also closed by Theatre Royal but couldn't see anything (that was about 7.15am)," he wrote.
