One occupant of the house said he saw blood on the floor as armed police escorted him out of the house following what police described as an "altercation".
As a result of the altercation, a man was arrested and charged with injuring with intent to cause grievous bodily harm.
Police could be heard telling the occupants of the house to put their hands in front of them on the lawn shortly after they entered about 2pm yesterday.
Seven patrol cars were seen in the street, and detectives and a scene of crime officer arrived about 3pm.
Police provided scant details of what led to the extensive response, only describing the matter as an altercation.
"One person was taken to hospital in a moderate condition and has since been released," Detective Sergeant Rob Hanna said.
"Police are speaking to both parties to establish exactly what happened."
It is understood an assault took place between two occupants of the boarding house and a weapon was possibly involved.
Residents of the house also appeared to be in the dark about what took place in their home, as many were asleep when police converged on the property.
"I was asleep," one occupant said.
Police had not informed him of what took place but he saw blood on the ground as he was escorted out of the house.
Another occupant, who was not home at the time of the altercation, said one of the men involved had moved into the house only in the past week.
There had been no issues with the man until yesterday’s incident.
Another resident said they were told by police not to return to the house until 7pm last night because scene examinations were taking place.
Residents of the street described the home as a halfway house and said other police call-outs to the home had occurred in the past.
One Leckhampton Court resident, who did not wish to be identified, said the home contained about 10 bedrooms and occupants frequently changed.
