Buildings in Leeds city centre have been evacuated after an “industrial incident” involving a crane, West Yorkshire Police has said.
And the incident is affecting trains going through the city’s station.
Roads have been closed around Riverside Way and access to the area has been restricted as police deal with the scene.
The force said no one was on the crane but did not give further details about the nature of the incident.
In a statement, the force said: “Access to the area has been restricted for pedestrians and road closures put in place. A number of buildings in the area are also being evacuated as a precaution.
“These closures are expected to be in place for some time and members of the public are advised to avoid the area and seek other routes.
“This is an ongoing incident and further updates will be provided in due course.”
West Yorkshire Fire & Rescue Service said it was called to reports of an unstable structure on Riverside Way at around 1.35pm.
A spokesperson for the service said: “Two crews from Leeds are in attendance dealing with the structure which is a large crane. The area has been cleared of people – access is restricted and road closures are in place.”
London North Eastern Railway (LNER) said trains running through Leeds station “may be cancelled or delayed” as emergency services dealt with an incident near the west end of the station.
The train operator said: “We’re working with our partners at Network Rail to get trains moving again as quickly as possible. We apologise for the inconvenience caused.”
