New York state’s Office of Children and Family Services recorded a complaint about a child being forced to sleep in the garage at NYPD officer Mike Valva’s house in 2019 — the same garage where the cop and his fiancee are accused of freezing-to-death another son — but Suffolk county child protective services ‘determined it to be “unfounded,” according to internal records reviewed by The Post.

The record, from a phone call logged on Feb. 27, 2019, states that Valva’s son Anthony was forced to sleep in the garage because he was urinating in his bed.

Valva and his fiancee Angela Pollina have been charged with murder for the hypothermia-induced death of his 8-year-old Thomas, who died on Jan. 17 after allegedly being forced to sleep in the same garage of the family’s Long Island home.

“For the past week, Anthony (9) has been coming to school with his clothes and backpack soaked in urine,” the OCFS record states.

“Anthony has been staying in the garage and is not allowed in his room due to him urinating in his bed … Step mother (Angela) and Father (Michael) are aware that the child is arriving at school soiled and fail to adequately address the concern,” the record says.

“The child’s feet and hands are bright red, but it unknown if this is as a result of the child being soaked in urine,” it adds.

The record shows the agency closed the claim after one day, calling it a “duplicate.” It’s not clear who reported it to the agency.

The memo is one of many narratives included in a record given to Anthony and Thomas’ mother, Justyna Zubko in May 2019.

The state OCFS then wrote to Zubko-Valva telling her the allegations were “unfounded.”

“The investigating district/agency has determine the report to be unfounded and the subject (perpetrator) and other persons named in the report(s) have been notified,” the letter says.

The confidential report was then sealed.

In a statement on Friday, the agency said: “While we cannot comment on the specifics of any investigation due to confidentiality requirements, OCFS has a statutory obligation to investigate any child fatality if that fatality is reported to the Statewide Central Register of Child Abuse and Maltreatment (SCR).”
