A 16-year-old boy and a 45-year-old man have been arrested on suspicion of arson after a fire that injured five people at a home.
Three children were among those treated after the blaze in Halifax Road, Rochdale, at about 20:30 BST on Wednesday, Greater Manchester Police said.
Officers previously described the incident as “disturbing” and said the victims’ injuries were not life-changing.
The two suspects have since been bailed pending further inquiries.
