A man's been arrested after an alert at the Arndale Centre in Manchester this evening.
Police say he's been taken into custody for questioning.
They were called to the scene following reports of a man with a knife.
No one has been reported to have been injured and police say there is not believed to be any wider threat to the community.
North West Ambulance Service confirmed crews were called to the scene.
But a spokesman said they've not taken anyone to hospital.
