The 17-year-old girl was admitted to Goa Medical College and Hospital at Bambolim near here following severe burn injuries and she is critical, Panaji police inspector Rajendra Prabhudesai said.
Police are trying to verify whether she tried to commit suicide or was set on fire, he said, adding that the Sub Divisional Magistrate (SDM) will be recording her statement soon.
The girl was with her grandmother at the time of the incident, he said.
She was allegedly raped by her teacher on December 29, 2011, at his residence where she had gone for remedial classes.
The accused had recently got bail by the Bombay High Court at Goa, after being behind bars for six months.
