A police officer has been slashed with a sword in a Manchester street attack.
He was treated in hospital after what Greater Manchester Police (GMP) called an "incredibly nasty incident" at about 13:50 BST on Sunday in Whalley Range.
The officer - who sustained wounds to his face and shoulder - is now recovering at home, the force said.
A 23-year-old man was arrested on suspicion of possession of a bladed article and assaulting a police officer.
A witness said the attacker ran towards officers with a 3ft sword held "up in the air" before being detained on Upper Chorlton Road.
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.
