A renowned German plastic surgeon has been jailed after causing the death of a woman after he sprinkled cocaine on his penis before she performed oral sex on him.

After 38-year-old Yvonne M's death, Dr Andreas David Niederbichler, 43, was found guilty of grievous bodily harm and subsequently sentenced to nine years in prison, Daily Mail reports.

According to reports, Yvonne, a hairdresser, was unaware Dr. Niederbichler had laced his genitals with the Class A drug when she performed the sex act at his home in Halberstadt, southeast of Hanover, last February.

Yvonne died soon after being admitted to a hospital despite being close to a medical facility. Dr. Niederbichler's apartment was located within the grounds of the plastic surgery clinic where he worked.

Yvonne had reportedly met the surgeon online and had been having an affair with him for some time, friends of hers told the court in Magdeburg, northwest of Halberstadt. She had even confided in them that she intended to leave her husband for the plastic surgeon.

It was later found that Dr. Niederbichler had carried out similar actions while engaging in sexual intercourse with other women, the court heard. On several occasions between 2015 and 2018, he allegedly put cocaine on his genitals before having sex with three other women. Prosecutors said he sometimes even laced their glasses of Champagne with the Class A substance.

Since 2016, Dr. Niederbichler has been the head physician at the Ameos Clinic in Halberstadt in the east-central German state of Saxony-Anhalt for Plastic, Aesthetic and Hand Surgery. Prior to that, the skilled doctor was appointed head physician at the Dessau Municipal Hospital for Plastic, Aesthetic and Hand Surgery.
