Turkish police are treating as suicide the death of an ex-British Army officer who helped start Syria's White Helmets, but his wife has been banned from leaving the country, local media said.
Police are analysing James Le Mesurier's hospital records where he sought help for mental health issues, the private DHA news agency said.
He founded Mayday Rescue, which helped train the White Helmets, a voluntary search-and-rescue group that was established to respond to bombings by the Syrian government in opposition-held areas.
Authorities have barred his wife, Emma Hedvig Christina Winberg, from leaving Turkey until the investigation has been completed, DHA reported.
Ms Winberg gave a three-hour statement to police yesterday, it added.
Turkish media have reported that Mr Le Mesurier recently sought medical help for stress, and was using sleeping pills and anti-depressants.
Ms Winberg has reportedly also told police that he had suicidal thoughts two weeks before his death.
The couple's domestic worker, who was in the building at the time, has told police she knew nothing about how Mr Le Mesurier died, according to DHA.
Mr Le Mesurier's body was repatriated to the UK yesterday.
