New details reveal that the Fulton County District Attorney filed a motion to seal Bobbi Kristina Brown's autopsy over fears of a potential flight risk for defendants and possible harm to witnesses, according to a court filing obtained by local Atlanta news station WSB-TV.

"The criminal investigation involving possible charges in this case is ongoing, no arrests have been made, and disclosure of the autopsy report and the above mentioned information at this time would compromise the integrity of the investigation and create risk of flight of possible defendants, and could pose a danger to witnesses involved in this case," the filing reads.

A judge granted the motion on Sept. 28.

While no arrests have been made in connection with Brown's death, a source told ET that the Georgia District Attorney will be convening a grand jury and is looking to possibly indict Brown's ex-boyfriend, Nick Gordon, on criminal charges.

In response to the report, a source close to Gordon's legal team tells ET, "Key evidence for the defense is now being delayed by the prosecution."

Gordon is currently facing a $10 million wrongful death civil suit filed by Brown's conservator, Bedelia Hargrove, alleging that he physically abused and stole thousands of dollars from her. In a subsequent amendment, it is alleged that Brown died after Gordon gave her a "toxic cocktail rendering her unconscious."

Gordon's lawyers have denied the allegations in the lawsuit, calling them "slanderous and meritless."

On Jan. 31, Brown was found unresponsive in her bathtub and was taken to North Fulton Hospital in Roswell, Georgia, where she was put on a ventilator to assist her breathing. She was later placed in a medically induced coma at Atlanta's Emory University Hospital. Nearly two months later, she was moved to a rehabilitation center, where she remained until June 24, when she was moved to the hospice center.

She died at Peachtree Christian Hospice in Duluth, Georgia on July 26 at 22.
