Martina Hingis and her mother questioned by police over alleged assault on estranged husband Thibault Hutin Martina Hingis has been questioned by Swiss police after her estranged husband said he was attacked by the five-time Grand Slam champion and her family. A Schwyz canton police spokesman, Florian Grossmann, has revealed that Hingis, her mother Melanie Molitor and her mother's boyfriend, Mario Widmer, were interviewed last week. Grossmann added that the canton justice department will decide possible further action, but no timetable has been set for a decision. French equestrian athlete Thibault Hutin claims he was attacked on Sept 23 at his home in Feusisberg. Hutin suggests Hingis and Molitor hit him, while Widmer allegedly struck him with a DVD player. Hingis, 33, came out of retirement this year to play doubles with Daniela Hantuchova at tournaments which included the US Open.
