Bangladesh police are investigating a case of suspected suicide by a seamstress who survived the collapse of a multi-storey building that killed more than 1100 people last year, officials say.
The 27-year-old woman, who police identified as Salma, apparently hanged herself in her rented home in a suburb of Bangladesh's capital, Dhaka, on Friday.
Police have recovered her body, and investigator Kamal Hossain said he was waiting for the autopsy report.
Doctors at the state-run Dhaka Medical College Hospital said they sent samples collected from Salma's body to another government-run research centre for viscera report.
Salma was one of about 2500 workers who survived the collapse of an eight-storey building that housed several garment factories.
Authorities said 1129 people died in the world's worst garment industry disaster, highlighting an industry with poor safety standards and often dangerous working condition.
Salma's husband, Mohammad Babu, said she suffered head injuries in the disaster, but had recovered.
Babu told police that he found Salma sound when he left home for work Friday morning.
Police detained him for questioning and were treating the wife's case as ''unnatural death''.
Hossain, the investigator, said he was sceptical about a theory spread by some local media that Salma committed suicide because she could not endure the pain caused by the wounds sustained in the building collapse.
