A police officer has been seriously injured after he was slashed with a sword while on duty.
A 23-year-old man has been arrested after the incident in Whalley Range, Manchester, on Sunday afternoon.
Police were called to the area at around 1.50pm after reports a man was using a weapon to threaten members of the public.
Once they arrived at the scene, officers tried to engage with the man, which resulted in one of them being slashed with a sword, Greater Manchester Police (GMP) said.
The man was detained after a taser weapon was deployed.
GMP said the injured officer was taken to hospital after sustaining serious injuries. He is not thought to be in a life-threatening condition.
The suspect has been arrested and held on suspicion of possession of a bladed article and assaulting a police officer.
A number of roads remain closed in the surrounding area and police advised people to avoid the area if possible.
Assistant Chief Constable Russ Jackson said: “The officers responded with immense bravery to this report and while the sergeant is making a good recovery, this was an incredibly nasty incident which could have been so much worse.”
He said the force had received “an overwhelming number of messages of support and best wishes for the officers involved,” adding: “We feel proud protecting and serving the communities of Greater Manchester.”
Police said they were responding to reports of an armed man threatening people about half a mile away in Demesne Road.
A number of streets around the scene of the attack were cordoned off while investigations continue.
