Ms Kumar was found with her legs tied to the tree but her hands unbound. A police officer said she was too weak to unchain herself. There were also reportedly marks from numerous other injuries on her body. She was wearing a see-through raincoat, an olive green shirt and worn-out brown trousers when she was found.

Police have registered a case of attempted murder against her former husband, who is accused of chaining her up before he escaped. Relatives of the couple are being interviewed by police.

Ms Kumar was transferred to Goa Medical College for specialist treatment after doctors raised concerns about her mental health.

A hospital official said: “She is out of danger, but she is suffering from severe depression and other mental health illnesses. We have found medical prescriptions in her possession suggesting she was on antidepressants.”

Documents found on Ms Kumar show that she was a resident of Tamil Nadu, a south Indian state, about 600 miles away from the forest where she was found. It is thought that she had been living in India for the past decade.
