Martina Hingis questioned by police over 'attack' on estranged husband

Five-time Grand Slam champion Martina Hingis has reportedly been questioned by Swiss police over allegedly attacking her estranged husband.

According to Schwyz canton police spokesman Florian Grossmann, Thibault Hutin has accused Hingis and her mother Melanie Molitor of hitting him, while her boyfriend Mario Widmer allegedly struck him with a DVD player.

It is understood that Hingis, Molitor and Widmer were interviewed by police last week, while the justice department are yet to make a decision with regards to taking further action, according to The Telegraph.

The attack is alleged to have taken place at Hutin's home in Feusisberg on September 23.
