Trains have been cancelled or delayed at Manchester Victoria after reports of a member of staff being threatened with assault.

Passengers have be warned of train cancellations and long delays to services.

The disruption is expected to last until 9pm tonight.

Commuters say there are no trains running in or out the station.

An announcement on the station referred to a member of staff being threatened with assault. Previous reports suggested the staff member had been attacked, but witnesses told the M.E.N. a man "shouted" at the worker, which prompted the station staff to walk out.

Northern and Network Rail described the incident as "a passenger disturbance". Northern has been approached for a further comment on the incident.

A statement posted on the Northern Twitter feed said: "Due to passengers causing a disturbance on a train at Manchester Victoria some lines will be blocked."

Another update on Network Rail said: "An operational incident at Manchester Victoria and also a points failure at Castleton is resulting in delays of up to 40 minutes to trains running through Manchester Victoria.

"Some trains will also be cancelled. Disruption is expected until 20:00"
