Describing how the man was carrying a "3ft tool or sword", he said the man 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 the head.
He added that before he was arrested, the man appeared to be "out looking for trouble" and was shouting during the incident.
