In what could be a major blow to India's Olympic preparations, Indian hockey captain Sardar Singh has been accused of sexual and mental harassment by an International hockey player of Indian origin, who has filed a written complaint against him with the Ludhiana police.

According to a report in the Indian Express, the woman claimed that she has been engaged to the Indian skipper for the past four years and alleged that Sardar “mentally, physically and emotionally tortured” her. The woman has also alleged that Sardar forced her to abort her child in 2015 against her wishes and later refused to marry her.

“I met him during the London Olympics and we got to know each other better after that. We got engaged but in 2015 I got pregnant. He told me to abort the child, which I did against my wishes and without getting support from anyone,” she told The Indian Express.

Ludhiana Police Commissioner P S Umranangal has confirmed the registration of the complaint and said that it is being verified and no FIR has been registered.

“The woman has alleged sexual harassment and filed a written complaint against national hockey captain Sardar Singh. The maternal family of the player lives near Bhaini Sahib and the woman has alleged that they met during visits to this religious sect guru. FIR has not been registered as the investigation is going on,” said Ludhiana Police Commissioner P S Umranangal to the Indian Express.

However, Sardar Singh, who has been participating in the ongoing 2016 Hockey India League, has come out and denied the reports of an assault.

"I know her, but it's wrong to say that I have assaulted her. I am sad to hear about such a thing." Sardar was quoted, as saying by NDTV.

“I will speak to my lawyer about the issue. My focus is on Rio Games," Sardar said.
