(Reuters) - The Federal Bureau of Investigation is interested in the investigation of MF Global Holdings Ltd, a person briefed on the matter said on Tuesday.
The person declined to give details. Regulators said on Monday that the company reported possible "deficiencies" in customer futures segregated accounts.
MF Global, which filed for bankruptcy protection on Monday, is the biggest U.S. casualty of Europe's debt crisis, and the seventh-largest bankruptcy by assets in U.S. history.
