Paris , France ( CNN ) -- French police are searching the home of the daughter of L'Oreal heiress Liliane Bettencourt , a spokeswoman from the prosecutor 's office in the Paris suburb of Nanterre told CNN Wednesday . Bettencourt 's daughter , Francoise Bettencourt-Meyers , went to court last month accusing a photographer of bilking her mother out of a billion euros . Bettencourt , who is France 's richest woman , allegedly gave the money to the photographer , but her daughter says she is not mentally competent to handle her own affairs . At the same time , police are investigating claims that Bettencourt 's adviser gave envelopes of cash to French President Nicolas Sarkozy and Labor Minister Eric Woerth.Police questioned Liliane Bettencourt on Monday . It was unclear whether the search at her daughter 's home and the questioning of Liliane Bettencourt were related , or to what case the search was tied . Woerth and Sarkozy have both denied the allegations , which resulted from secret recordings that surfaced last month . The recordings , allegedly made by Bettencourt 's butler , also refer to a bank account in Switzerland containing 80 million euros ( $ 98.3 million ) , which had not been reported on Bettencourt 's taxes . Woerth will be questioned by police at some point , a spokeswoman for the prosecutor 's office said last week . No date for that has been set . Woerth 's wife , Florence , was questioned last week , the spokeswoman said . The secret recordings published last month revealed that Florence Woerth was , until late June , the deputy to Bettencourt 's financial adviser , Patrice de Maistre . Bettencourt 's former bookkeeper , Claire Thibout , elaborated on the allegations in an interview this month with a French investigative website . She said she prepared envelopes of cash that were to be given to Sarkozy and Woerth , who previously worked in the Budget Ministry and was in charge of reforms to France 's retirement system . Thibout 's lawyer told French news agency Agence France-Presse this month that de Maistre once asked his client for 150,000 euros ( $ 188,800 ) and said he would give it `` discreetly '' to Woerth at a dinner . Thibout testified before a judge about the allegations earlier in July . The French newspaper Le Monde published her testimony , in which she repeated her allegations against de Maistre and said she regularly withdrew large sums of money at his request . Among other claims is that Sarkozy 's 2007 presidential campaign received money from Bettencourt in excess of campaign finance limits .
