PROVO — A Provo woman has been arrested on suspicion of sexually abusing her young daughter as a tactic in a custody dispute.

The Daily Herald of Provo reports Tiffany Petrossi was booked Thursday on charges of aggravated sexual abuse of a child and giving false or inconsistent material statements.

According to a police affidavit, she admitted using a jagged fingernail to injure her daughter in 2009. But at the time, she accused the child's father, Jesse Huffaker, of committing the sexual abuse.

The affidavit states the case against Huffaker was dismissed after investigators performed an analysis of the evidence and found no male DNA.

In March, the father approached police and expressed his suspicion that the woman had committed the abuse in order to influence their custody dispute.
