Anaïs says police told her they found a spreadsheet of the alleged victims on Nègre’s computer, entitled Experiments P, which was how they found her.
The document, she says, noted the time the women arrived for their interviews, when the diuretic was administered, how long it took before they urinated, and what underwear they were wearing.
Looking back, Anaïs is now convinced the strange taste in the coffee Nègre made her was the diuretic.
The investigation into Nègre began in June 2018, when he was caught by a colleague taking a photograph of a woman from beneath a table, the prosecutor’s office said in a statement released in February this year.
He was initially suspended from his job as regional director of cultural affairs before being sacked by the Ministry of Culture in 2019.
Prosecutors said that in 2018 he told investigators he had “imposed humiliating situations on women” during job interviews.
Many of the women say the first time they realised they may have been victims was when police contacted them.
Some came forward when they saw Anaïs and other accusers in media reports.
Nègre, who is in his 60s, is now under formal investigation on charges that include drugging, invasion of privacy and sexual assault. He is awaiting trial.
The BBC put the allegations contained in this article to Nègre through his lawyer, but he declined to comment.
Another person named in Nègre’s notes was Marie-Hélène Brice. He interviewed her for a job at the Ministry of Culture in 2016 in Strasbourg, where he was then working.
She says he told her she looked stressed and suggested they take a walk outside to “calm her nerves”.
But as they strolled along the canal, Marie-Hélène, like Anaïs, felt an uncontrollable need to urinate, which began to cause her pain.
She says Nègre told her that he knew of a public toilet nearby, but when they arrived at the location there was no toilet.
“I was really starting to suffer… pains to the point that I was white, pale, I had tears streaming down,” she says.
Marie-Hélène says she had no choice but to urinate in public. She says Nègre offered to shield her with his jacket.
“I was terribly embarrassed,” she says. “He didn’t take his eyes off me.”
Marie-Hélène says that for years she felt ashamed.
Like Anaïs, she was also contacted by police who told her she was among Nègre’s alleged victims. “It was a very big shock,” she adds.
