"It was brought to our attention earlier this week by the firm that manages the Healing Assistance Fund that there are possible fraudulent claims being made," MSU Spokesperson Emily Guerrant said in the release. "MSU has decided to halt all further payments while the situation can be investigated."

Guerrant said that the university does not currently have specifics on the investigation.

Additionally, MSU filed a lawsuit on Thursday against all of its insurance carriers "regarding the policies and coverage for sexual assault claims," according to another university statement.

The university announced in recent months that it'll rely on its insurance companies to assist in paying for the $500 million settlement made in May with the survivors of Nassar's sexual abuse.

"We are suing our carriers, including our largest carrier United Educators, for failing  to honor their policies," Robert Young, MSU's general counsel, said in the statement. “It is disappointing  and unfortunate we have to go to court on this matter, but we are hopeful this lawsuit will bring us to speedy resolution and that the insurance companies will honor their contractual obligations."

A breakdown of the lawsuit was not immediately available, as the court in which it was filed was closed and Guerrant told the Detroit Free Press she didn't have the suit on hand.
