'STAR TREK: The Motion Picture' and '7th Heaven”' TV pastor dad STEPHEN COLLINS reportedly confessed to his estranged wife his alleged sexual predator misdeeds and it’s on tape.

New York Police Dept. is actively conducting criminal charges Collins may have involved sexual contact with multiple young children.

In the middle of an ugly divorce from actress Faye Grant, Collins confessed in 2012 he had molested and exposed himself to underage girls some years prior

Trying to resolve their marriage difficulty, they went to a therapist where Collins was said to be very specific about his alleged incidents.

According to reports, Collins was unaware he was being recorded by his wife at the therapy sessions. However, her lawyers said it was okay because under the laws of the State of California it’s legal to secretly record conversations to gather evidence the subject committed a violent felony — and molesting children under 14.

On the tape, he reportedly confesses to molesting an 11 year of New York City girl – said to be a relative of his first wife. He describes in lurid details several other alleged incidents as well.

The NYPD is in possession of the tape, and detectives from the Special Victims Unit have flown to Los Angeles to interview Faye Grant and other potential witnesses

A law enforcement official leaked that there are "at least 3 victims" and the investigation is "inappropriate sexual contact with minors."

Although decades have passed since the molestation, allegations the cases can still be prosecuted because the statute of limitations runs from the date of reporting, legal insiders say.

A high ranking member of Screen Actors Guild often is on set with very young actresses. In addition to "7th Heaven," he was appeared on the ABC Family show "The Fosters," and the recent show, "Revolution" which alaso employed young actors.

Media has contacted Collin’s rep. Their response – ‘no comment’.
