The Swiss bank is owed about $3 million by Sanomi, who was a guarantor for a credit facility extended to one of his companies, Credit Suisse’s lawyer Andrew Brown said in written submissions to a London court last week. Three properties owned by Sanomi including apartments in Chelsea, west London, and Belgravia, in the heart of London’s diplomatic quarter, have already been identified as assets that may have to be forfeited if he loses.

Sanomi, who wasn’t represented in the London court, declined to comment through a spokeswoman. Sanomi “has not put in any defense or objection to the charging orders,” Brown said.

Sanomi’s company, Taleveras Energy, trades more than 100 million barrels of crude oil annually and is targeting biofuel investments, Bloomberg reported in 2017.

Credit Suisse isn’t the only lender targeting Sanomi’s assets. Banque Cantonale de Geneva has already made a freezing order against the London properties. ING Groep NV is also suing Sanomi for Taleveras’s unpaid debts, according to separate court documents filed in October.

The jet taken from Sanomi was listed for sale.
