Brit motor sports boss' sex session S and M death re-enacted by dominatrix

London, July 2 (ANI): The Belgian dominatrix, charged over the S and M death of a British motor sports boss, has re-enacted the fatal bondage session for cops by using a dummy.

Ira Van Denderen, 46, who is known as Mistress Lucrezia to her clients, took part in a two-hour filmed reconstruction of the tragedy at her 300,000 pounds mansion, dubbed Torture Towers, near Antwerp, the Sun reported.

She had been quizzed there about the final hours of father-of-one Robin Mortimer, 58, from Coventry, who had collapsed and died nine days ago during a 600 pounds sado-masochistic sex session with her.

Her sidekick Vicky Vanherle, 36, also took part in the police reconstruction of the death of Mortimer, a motorcycle racer who switched to sports car racing in 1989, and who was head of the RPM Motorsport team.

Investigators want to know if he was killed by the anaesthetic nitrous oxide, laughing gas, used to prolong the brutal sex games.

Their film of Van Denderen includes a tour of her torture chamber and may be used at her trial next year.

She and Vanherle are on remand facing charges of assault and battery leading to death, without intent to kill. They face ten to 15 years in jail if convicted. (ANI)
