Police on Thursday detained Asian Games gold medalist Pinki Pramanik after her live-in partner accused her of rape and claimed that the athlete, who refused gender test, was a male.
Anamika Acharya, in her June 13 complaint, said Pramanik had slept with her, promising marriage but later refused.
"Acharya said Pinki had raped her and that she was not a woman but a man," said Subrata Bandopadhyay, DC headquarters of Bidhannagar.
Under Indian law, a woman cannot be accused of raping a woman, as penetration has to occur for "rape" charge to hold.
The two were taken to the court on Thursday, where the police sought permission for a medical check on Pramanik.
"She refused medical test," said Rajeev Kumar, commissioner of Bidhannagar Police, in-charge of the area where Pramanik and Acharya live.
"We're trying to figure out what should be done next," Bandopadhyay said. A gender test isn't mandatory for medal winners, said an Athletics Federation of India (AFI) member on condition of anonymity.
AFI secretary CK Valson said they would wait for the medical and police reports before taking any action.
He said they would inform the International Association of Athletics Federations if the Eastern Railways runner was found to be a male.
IAAF rules were not clear on if Pramanik could be stripped off her medals, he said.
On and off the field, the 26-year-old has had a controversial run.
In November 2004, she was arrested for illegal possession of firearms. Three years later, she was nowhere to be found after winning the heats at a national event.
