Paris’ GFG headquarters were raided by French authorities.

Sanjeev Gupta’s GFG Alliance offices and an aluminum smelter were seized by French police as part of an ongoing investigation into charges of money laundering and corporate asset mismanagement.

During their visit last week, French officials accessed GFG records and files, according to Gupta’s firm. “We vehemently deny any allegations of misconduct and will continue to fully cooperate with the French authorities to quickly resolve this matter,” GFG added.

The UK’s Serious Fraud Office is already investigating Sanjeev Gupta’s GFG Alliance for fraud and money laundering. A year ago, Greensill Capital UK went bust. Now, GFG’s financing arrangements with Greensill Capital UK are under examination

Several GFG assets, including the Dunkirk smelter and two significant steel mills, were located in France before Greensill’s demise.

Separately, the French National Police visited Aluminium Dunkerque’s offices in Loon-Page, in northern France. Aluminium Dunkerque said it will “fully cooperate” with any French investigation.

The Paris prosecutor’s office declined to comment.

The raids, first reported by the Financial Times, add to the pressure on Sanjeev Gupta. The matter was handed over to the French unit that fights corruption and financial crime after reports from public officials.
