City Comptroller Scott Stringer says his office will lead a new probe into the Administration for Children’s Services, following the death of a six-year-old Harlem boy earlier this week.

Stringer's office conducted an audit in June, finding that the agency routinely failed to check in with victims of abuse or neglect, and did not evaluate homes for signs of domestic violence.

The Comptroller's probe will determine if ACS implemented any of the reforms his office recommended.

Five ACS employees have been placed on desk duty following Zymere Perkins' death.

Police say last spring, a school nurse had notified authorities after she found a bruise on the boy's leg.

The NYPD and ACS both questioned the family, but did not have enough evidence for an arrest.

His mother and her boyfriend were arraigned on charges of endangering the welfare of a child.

The Department of Investigation is also looking at how ACS handled the case.
