A spokesman for Level Global acknowledged the raid took place Monday."We can confirm that agents from the Federal Bureau of Investigation visited our offices this morning as part of what we believe to be a broader investigation," the spokesman said in a statement. "We are cooperating fully with the authorities and, at the same time, we are fully operational and continue to work diligently for the benefit of our investors."A gaggle of financial reporters, some from as far away as Norway, staked out the Greenwich offices of Level Global at 537 Steamboat Road before Monday's closing bell.What they found were empty parking spaces, locked doors and not a single trader or company executive."I haven't seen or talked to anybody, FBI or otherwise," said John Margenot, whose family owns the building and is the nephew of the former first selectman by the same name.Located across the street from the yacht-lined Delamar Greenwich Harbor hotel and next door to several unoccupied townhouses fetching $8 million, the four-story brick building is home to several investment firms.via Feds raid 3 hedge funds linked to trading probe - GreenwichTime.
