French investigators searched ​the Paris offices of Swiss bank Edmond de Rothschild as part of an inquiry into alleged corruption ‌involving a French diplomat named in documents linked to the late sex offender Jeffrey Epstein, prosecutors said on Tuesday.

The name of Fabrice Aidan, a middle-ranking French diplomat who was seconded to the United Nations from 2006 to 2013 and later worked at the bank, appeared in more than 200 documents ​released by the US Justice Department.

These include emails he is alleged to have sent Epstein between 2010 and 2016 ​from his personal and UN accounts.

Some of the emails reviewed by Reuters show the transfer of ⁠UN Security Council briefings and other confidential documents to Epstein during that period.

Aidan has denied wrongdoing, and his lawyer did not ​immediately respond to requests for comment.

The French Foreign Ministry said it had completed an administrative investigation, performing about 30 interviews. The ​ministry said all current and former staff members who had been summoned to its investigation had cooperated, adding that it was available to judicial authorities and was considering disciplinary proceedings.

The search was carried out on Friday in the presence of Ariane de Rothschild, the Swiss bank’s boss, a source ​close to the bank said.

Edmond de Rothschild was cooperating fully with the justice system in the investigation led by the financial ​prosecutor, the same source said, adding that an internal inquiry had been launched as soon as suspicions emerged concerning the former employee, who worked ‌at the ⁠bank from 2014 to 2016.

Accusation of ‘passive corruption’

The investigation is being led by officers from France’s central office against corruption and financial and tax offences, who questioned Aidan in a voluntary interview in late February.

The French financial prosecutor’s office said it was investigating accusations of passive corruption of a foreign public official and complicity in that crime, targeting ​Aidan in particular.

When asked if ​it was looking into Epstein ⁠links with the Geneva-based Edmond de Rothschild, Swiss financial regulator Finma said it considered all reliable information in its supervision and conducted in-depth reviews when in doubt about the integrity of business ​activities.

Swiss federal prosecutors did not immediately respond to a request for comment on whether they ​were also investigating. ⁠A spokesperson for the Geneva prosecutor’s office declined to comment on whether any measures were taken in the city.

Ariane de Rothschild also appeared in the files released by the US Justice Department in January, which showed she kept up a years-long personal correspondence with Epstein before ⁠his 2019 ​arrest.

After the files were released, a spokesperson for the bank said that Epstein ​was a business acquaintance of de Rothschild from 2013 to 2019. De Rothschild had no knowledge of Epstein’s conduct, the spokesperson claimed.
