The protesting wrestlers on Wednesday demanded lie-detector test on Wrestling Federation of India (WFI) chief Brij Bhushan Sharan Singh after he claimed innocence to allegations of sexual harassment.

Some of the country’s top wrestlers, including Olympic medallists Bajrang Punia and Sakshi Malik and Asian Games gold winner Vinesh Phogat, have been protesting at Jantar Mantar here for over a fortnight, demanding arrest of Singh for allegedly sexually harassing seven women wrestlers, including a minor.
