Former TV gumshoe Vincent Parco plans to sue the Brooklyn District Attorney’s Office over its announcement of his prison sentence for illegally filming a steamy sexcapade on behalf of a pedophile — claiming the press release unfairly paints him as a child sex abuser.

Parco, the 69-year-old former “Parco P.I.” star, alleges in a notice of claim filed on Wednesday that the Brooklyn DA’s June 14 press release “falsely” suggests the ex-private eye knowingly took part in a scheme to prevent a child-abuse victim from testifying against her abuser — an allegation, he asserts, that is “worse” than actually abusing a child.

“There is only one thing worse than abusing a child … falsely accusing someone of abusing a child, since it diverts attention to a fictitious problem and wastes scarce investigatory resources that are dedicated to this scourge,” the notice states.

Parco was convicted in May of unlawful surveillance and promoting prostitution for surreptitiously filming the husband of a child-sex abuse victim having sex with two prostitutes as part of a blackmail scam to stop the victim from testifying against her abuser, Samuel Israel. He was sentenced to one to three years behind bars.

Parco claims in the notice that he was hired to investigate a “married philanderer” and that he had nothing to do with a plot to intimidate a minor. His lawyers had made a similar argument at trial, but a Brooklyn jury didn’t buy it.

In the DA’s June 14 news release, entitled “Private Investigator Sentenced to 1 to 3 Years in Prison for Unlawful Surveillance and Promoting Prostitution as Part of a Scheme to Keep Victim Of Child Sexual Assaults from Testifying Against her Abuser,” the office states that Parco was “hired in connection with a scheme to pressure a woman to stop cooperating in the prosecution of a man who sexually abused her as a child.”

Israel was previously convicted of sexually assaulting a 10-year-old family member.

Parco is in the process of appealing his conviction, his lawyer, Peter Gleason, said.

The Brooklyn DA’s office did not immediately provide a response to the notice.
