Investigations are under way after two terraced houses used as flats were severely damaged by a large fire.
The blaze tore through the buildings on Park Road, in Springfield, at around 6pm on Saturday July 2.
Greater Manchester Fire and Rescue Service (GMFRS) said everyone living at the block of flats was accounted for and no-one was in the building at the time of the blaze.
Six fire engines and an aerial platform were needed to bring the flames under control as firefighters wearing breathing apparatus tackled the incident.
Crews used ladders to fight the fire from the outside while colleagues entered the building with hose reels.
Fire crews and police officers remained at the scene throughout the night and investigators from GMFRS and Greater Manchester Police (GMP) visited the building on Sunday morning.
Sniffer dogs were also brought in to check if any accelerants were used.
The outcome of the investigation is not yet known.
The fire service said the structure of the building is also being assessed. The flats have been boarded up and the landlord visited on Sunday afternoon.
The North West Ambulance Service (NWAS) attended but was not needed.
A technical rescue unit was also sent to the scene as a precaution.
