A second woman has been arrested by police investigating the death of a woman in a house fire in Birmingham.
Nusarat Bugum, 36, was killed in a suspected arson attack on a property in Speedwell Road, Edgbaston, just before 07:00 GMT on Monday.
West Midlands Police said a 30-year-old woman from Small Heath had been arrested on suspicion of murder.
Detectives have been given a further 36 hours to question a woman, 38, who was arrested on Monday, the force said.
A 21-year-old man, who was also arrested on Monday, has been bailed pending further inquiries.
Three other people were injured as they tried to escape from the fire.
A man, 34, and two women, aged 55 and 23, remain in hospital, but West Midlands Police said their injuries were not life-threatening.
Officers said Ms Bugum, who arrived in the city from Pakistan six months ago, was in the UK to visit her parents who both live in Birmingham.
Police said while the precise cause of the fire was yet to be established, it believed the fire was set deliberately near the front door in "a targeted attack".
