The woman has not yet been formally identified.
Senior Sergeant Stephen McIntyre said they would not know the cause of death until a post mortem examination was conducted on Tuesday.
“Until such time as the post mortem has been conducted we’re going to continue to treat the matter as suspicious,” he said.
He refused to comment on the woman’s injuries or if she lived at the house.
Police were alerted to the death by a man who called from a public telephone, down the street, which is now being treated as a secondary crime scene.
“We haven’t identified that male. So at this point in time, I’d like to ask him to come forward and make himself known to police,” Senior Sergeant McIntyre said.
“There’s nothing to suggest he had anything to do with the death of this woman and it may very well be that he is just someone coming to visit and found the dead person and contacted police.”
Senior Sergeant McIntyre was asked about what appeared to be a blood stain in the telephone booth, but said he had not seen it and did not believe it was connected to the death.
