DETROIT (AP) — Olympic gold medalist Simone Biles and dozens of other women who say they were sexually assaulted by Larry Nassar are seeking more than $1 billion from the FBI for failing to stop the sports doctor when the agency first received allegations against him, lawyers said Wednesday.

There’s no dispute that FBI agents in 2015 knew that Nassar was accused of assaulting gymnasts, but they failed to act, leaving him free to continue to target young women and girls for more than a year. He pleaded guilty in 2017 and is serving decades in prison.

“It is time for the FBI to be held accountable,” said Maggie Nichols, a national champion gymnast at Oklahoma in 2017 to 2019. An email seeking comment was sent to the FBI.

Under federal law, a government agency has six months to respond to the tort claims filed Wednesday. Lawsuits could follow, depending on the FBI’s response. In May, the Department of Justice (DOJ) said that it would not pursue criminal charges against former agents who were accused of giving inaccurate or incomplete responses during an investigation by the DOJ’s inspector general, an internal watchdog.

“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,” said former University of Michigan gymnast Samantha Roy.

The approximately 90 claimants include Biles, Aly Raisman, and McKayla Maroney, all Olympic gold medalists, according to Manly, Stewart & Finaldi, a California law firm. Separately, 13 claims were filed by others in April.

“This was not a case involving fake $20 bills or tax cheats,” attorney Jamie White said. “These were allegations of a serial rapist who was known to the FBI as the Olympic U.S. doctor with unfettered access to young women.”

Failures by federal law enforcers have led to major settlements before. White noted the 2018 massacre at Florida’s Marjory Stoneman Douglas High School. The FBI received a tip about five weeks before 17 people were killed at the school, but the tip was never forwarded to the FBI’s South Florida office. The government agreed to pay $127.5 million to families of those killed or injured.

In the Nassar case, Indianapolis-based USA Gymnastics told local agents in 2015 that three gymnasts said they were assaulted by Nassar, a team doctor. But the FBI did not open a formal investigation or inform federal or state authorities in Michigan, according to the inspector general.

In 2016, Los Angeles agents began a sexual tourism investigation against Nassar and interviewed several victims, but also didn’t alert Michigan authorities, the inspector general said. Nassar wasn’t arrested until fall 2016, during an investigation by Michigan State University police. He was a doctor at Michigan State. The Michigan attorney general’s office ultimately handled the assault charges against Nassar, while federal prosecutors in Grand Rapids, Michigan, filed a child pornography case.

In remarks to Congress last year, FBI Director Christopher Wray acknowledged major mistakes. “I’m especially sorry that there were people at the FBI who had their own chance to stop this monster back in 2015 and failed,” Wray told victims at a Senate hearing. “That’s inexcusable.”

At that same hearing, Biles, widely considered to be the greatest gymnast of all time, said an “entire system” enabled the abuse. Maroney recalled “dead silence” when she talked to FBI agents about Nassar.

Michigan State University, which was also accused of missing chances over many years to stop Nassar, agreed to pay $500 million to more than 300 women and girls who were assaulted by him. USA Gymnastics and the U.S. Olympic and Paralympic Committee made a $380 million settlement.
