A 2010 raid of now-defunct hedge fund Level Global was "based completely on a lie," an attorney for the fund's manager David Ganek argued on Friday.
Ganek on Thursday sued prosecutor Preet Bharara and U.S. officials, claiming they fabricated accusations against him that prompted the search.
"As a result of being named in the warrant, as a result of how public it was, he was forced to close down his business," Ganek's lawyer Nick Brustin told CNBC's "Closing Bell."
