Belgian-Israeli diamond trader and 65-year-old billionaire Ehud Arye Laniado died of a heart attack during a penis enlargement procedure at the Saint-Honoré-Ponthieu aesthetic clinic in Paris.

A well-known surgeon who operated on wealthy clients, known as Guy X, performed procedures on Ehud two to four times a year, each costing tens of thousands of euros.

The owner of Omega Diamonds underwent these procedures outside the clinic’s official schedule. He received injections into the penis to create a visual enlargement effect. After his death, an investigation was immediately launched into possible involuntary manslaughter, but it later shifted to charges of failure to assist a person in danger, violations of drug regulations, and illegal medical practice.

A Paris court suspended Guy X’s medical license and sentenced him to 15 months in prison. His colleague, who substituted for him that evening, received a 12-month suspended sentence.

Both surgeons were permanently banned from practicing medicine and were ordered to pay €50,000 and €20,000 respectively, according to Le Parisien.
