A police officer has been left with "serious injuries" after being slashed with a sword in Manchester on Sunday.
A 23-year-old man was arrested after the officer was slashed with a sword in Whalley Range at about 1.50pm, Greater Manchester Police said.
The officer is currently in hospital with "serious injuries", the force added.
A number of roads around Demesne Road, the residential street where the incident happened, have been closed off.
Footage of the incident showed two police vans and a car blocking Demesne Road as officers get out of the vans, some with riot shields.
A man can be seen running down from a terraced house and the officers can be seen backing off as one points a stun gun at him.
They get the man on the ground on his back.
He can then be seen brandishing what looks like a sword from side to side before one officer uses his baton to subdue and then arrest him.
One witness, Haroon, said he saw a man being arrested by officers on Upper Chorlton Road at about 2.50pm, who had been "attacking the police".
He said the man was carrying a "3ft tool or sword" and 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 said.
"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 that he saw them bleeding – one from the lip or nose, and another on top of their head.
He said the man was shouting during the incident.
Greater Manchester Police confirmed a man was arrested at around 2.10pm on Sunday.
