Jerry Sandusky "inappropriately touched" one of his grandsons, the ex-wife of his son Matthew has claimed on the day a judge eased bail restrictions on the former Penn State defensive coach despite child sex abuse charges.

Jill Thomas criticized the judge’s ruling Monday that her former father-in-law — who is charged with 52 counts of child sex abuse — could see his grandchildren, and said she did not feel safe letting him see her three sons.

"I cannot understand how a court could place the desires of someone who is criminally charged with sexually abusing children above the safety of children," Thomas, who is locked in a custody battle with Matthew Sandusky, said in a statement.

The Philadelphia Inquirer reported Tuesday that Thomas sent a statement sent to reporters hours after the ruling saying that psychologists who had treated her 5-year-old son "could not rule out that Jerry Sandusky was grooming him for sexual abuse"

Sandusky’s attorney, however, told the Philadelphia Inquirer that his client was being used as a chip in the custody battle.

However, Thomas said her children told her of the inappropriate touching only after Sandusky was granted access Monday, ABC News reported, adding that she said the judge's summary did not accurately or completely reflect the danger Sandusky posed to children.

"Although I have kept silent up until now to protect my children and my family’s privacy, I can no longer keep silent about Jerry Sandusky’s request to be permitted to see my children," Thomas said.

"Shortly after news of the child sexual abuse criminal charges against Jerry Sandusky became public, my children reported to me that Jerry Sandusky, their grandfather, had inappropriately touched my son. I was devastated by this news."

She said she reported the claim to authorities, who decided there was not enough evidence to charge Sandusky with a crime.
