KABUL, Afghanistan — He was their nightmare, the young, female Afghan soccer players say: a menacing 57-year-old with two wives who locked the door to his back office with a biometric keypad that only he could open.

Many of those young soccer players, members of the women’s national team, lined up to accuse the man, the president of Afghan soccer, Keramuddin Keram, of sexually assaulting them in a bed he kept in that room, and elsewhere, charges they made both in public statements and to Afghan prosecutors. Women who rebuffed his advances were labeled lesbians and expelled from the team, according to eight former players who said that had happened to them.

Three months later, however, the investigation into sexual abuse in Afghan soccer is stalled, amid fears it will never proceed. It has yet to result in any criminal charges.

One of Mr. Keram’s accusers, the soccer player Khalida Popal, said he had actively pursued women who testified against him in Afghanistan, warning them to withdraw the charges. And witnesses like her who live in exile have not been interviewed in person by Afghan investigators, as required by law, because so far the investigators have not been able to get visas.
