A British police officer who was attacked with a sword has been discharged from hospital, Greater Manchester Police (GMP) said.
The force said a 23-year-old man has been arrested following the incident in Whalley Range in Manchester today, and that the officer is recovering at home.
One eyewitness described seeing a man detained on Upper Chorlton Road who had been "attacking the police" and carrying a 3ft sword.
GMP said they were called to Demesne Road at 1.50pm to reports of a man with a knife, and confirmed an individual was arrested at around 2.10pm.
The force told the Press Association that the injuries the officer sustained during the incident, in which he was slashed with a sword, were to the face and back.
One witness who gave his name as Haroon said he saw a man being arrested by officers on Upper Chorlton Road, who had been "attacking the police".
Describing how the man was carrying a "3ft tool or sword", he said he ran across the road into the front garden of a property on the street.
"From there the police tried to stun him because he wasn't dropping the weapon... I don't know if the officer made a successful tase," he added.
"He became even more aggressive and ran towards them with the weapon up in the air... from there the officers tackled him, pushed him over and then I think he ran backwards and fell over.
"That is when the officer tried to disarm him, and you could see them using their weapons (batons) and they were hitting him on the legs - and he was not letting go.
"You could see him still hitting back while he was on the floor."
He said the man "had hit a couple of the officers", and added that he saw them bleeding - one from the lip or nose, and another at the top of their head.
When pressed on the demeanour of the man before being arrested, he said it was like he was "out looking for trouble", and was shouting during the incident.
A number of roads were closed around the scene in Demesne Road, GMP said.
