Troubled Bermuda-based telecommunications company Global Crossing Ltd. is being investigated by the Federal Bureau of Investigation, Reuters reported yesterday.

Global Crossing, which filed for the fourth largest bankruptcy in US history last month, is also being investigated by the Securities and Exchange Commission.

Global Crossing said the US Securities and Exchange Commission had

launched a formal Global Crossing investigation, after a letter from a former

Global employee alleged that the firm had used improper accounting methods that

artificially inflated revenues.

Global Crossing said it would not comment on the probe by the FBI, but a

spokeswoman said the company had received notice of the SEC investigation in a

letter dated February 6, Reuters said.

``Our policy is and always has been to cooperate with any investigation by

appropriate authorities,'' Global Crossing spokeswoman said Becky Yeamans told

Reuters.

An FBI spokesman had no comment when asked about the Global Crossing

investigation and added: ``As a policy, we do not confirm or deny

investigations.''
