A dominatrix offering bondage, humiliation and torture has been arrested after a British motor racing boss was found dead in Belgium.

Robin Mortimer, 58, was discovered in the village of Brecht, near Antwerp, police said.

Two women calling themselves Mistress Lucrezia and Mistress Juno have been arrested on suspicion of assault leading to death, without intending to kill.

The results of a post-mortem examination are expected to shed light on how the married father-of-one died.

A statement released on behalf of Mr Mortimer's family said relatives believed the racing driver died of natural causes in his sleep.

It read: "Robin Peter Mortimer, owner of RPM Motorsport, sadly passed away late on Tuesday June 22, aged 58.

"It is understood that Robin died of natural causes in his sleep at a hotel in Belgium while travelling with his team en route to Spa Francorchamps."

The son of Grand Prix driver Charles Mortimer leaves behind his wife Bridget, known as Biddy, and son, motor racing champion Alex Mortimer, who hopes to compete at the Spa circuit this weekend in honour of his father.

A spokesman for the Foreign Office said: "We can confirm the death of 58-year-old British man Robin Mortimer near Antwerp on June 22. Next of kin are aware and we are providing consular assistance."
