Four time Olympic gold medalist Simone Biles is one of over 90 women suing the FBI for more than $US1 billion

Lawyers for the group, which also includes gold medalists Aly Raisman and McKayla Maroney, say the FBI failed to address allegations of sexual assault towards former U.S national team doctor Larry Nassar.

The FBI was aware of allegations against Nassar as far back as 2015 but failed to address them, leaving the doctor free to target victims for over a year.

The doctor is now serving life in prison without parole after pleading guilty to multiple charges of criminal sexual misconduct.

In May the U.S justice department said it would not pursue charges against the agents who failed to investigate Nassar.

Former national champion gymnast Maggie Nichols says “it is time for the FBI to be held accountable”.

The agency has declined to comment, and has six months to respond to the claims filed on Wednesday.

But FBI director Christopher Ray has previously labelled the agency’s mistakes as “inexcusable”.

“If the FBI had simply done its job, Nassar would have been stopped before he ever had the chance to abuse hundreds of girls, including me”.

Thirteen Nassar victims filed similar claims against the FBI earlier in the year.

In 2018 Michigan state university agreed to pay $US500 million to over 300 victims for failing to stop the predator.
