A professional female boxer from Brazil – a three time world championship challenger – has been arrested on suspicion of killing her wealthy Swiss hotelier husband.

Brazilian born Viviane Obenauf, 34, is accused of beating her husband Thomas, 61, to death in his restaurant Des Alpes at Interlaken in Switzerland on October 19, DailyMail reports.

She was arrested this week and is currently in investigative custody after the victim died from a ‘sustained violent assault’.

The couple had only married in January and detectives are now looking into claims that she was responsible for his death.

People who knew her said that she was not shy of taking on women or men outside of the ring if she lost her temper.

According to a report in Swiss newspaper Blick, she had been arrested in London when a man in a nightclub tried to grope her bottom while she was celebrating her 30th birthday and she punched him in the face.

The incident meant that she spent several hours in a jail cell in October 2016.

Obenauf was born in Rio de Janeiro, and as a youngster she played football and was an Olympic gymnast before turning to boxing at the age of 18.

She began working in the gastronomy industry in Switzerland after retiring from the sport and then later opened her own gym.

On her homepage she says she has a son called Calvin and spending time with him is the best thing she enjoys in a day.
