An official accusation alleging that Zambia's head coach Bruce Mwape sexually assaulted a player at the Women's World Cup is being looked into by Fifa.

Mwape is accused of touching one of his players' chests while they were in New Zealand for a training session on July 29.

"A complaint has been received," a Fifa spokesperson said.

However, the Football Association of Zambia (FAZ) stated that it was a "surprise" and that "it has not received any such complaint".

Two days prior to Zambia's last group match against Costa Rica, which they won 3-1 for their first World Cup triumph, the alleged event is believed to have occurred during a training session.

The spokesperson for Fifa further stated, "Fifa takes any allegations of misconduct extremely seriously and has a clear process in place for anyone in football who wants to report an incident."

After placing third in Group C, Zambia was eliminated and has since gone home.
