A hedge fund deceived police officers and firefighters who responded to the Sept. 11 terrorist attacks and cost them millions earmarked for their health, New York’s attorney general and a federal regulator alleged in a lawsuit Tuesday.

The hedge fund, RD Legal Capital, in some instances allegedly charged the first responders interest rates above 250% to advance federal cash due for the medical care of sick workers, according to the suit. RD Legal similarly defrauded former National Football League players in line for a $1 billion settlement over head injuries suffered in their careers, authorities alleged.
