A mortified Queens couple says NYPD cops ransacked their home — and left the wife’s sex toys dumped in their 5-year-old daughter’s bedroom — during a 2012 investigation.

In a lawsuit filed in Brooklyn federal court on Friday, James and Gina Goldring say the cops left the naughty items behind after spending hours in the home probing the dad’s accidental shooting of their teenage son.

The cops were furious that Gina told James to keep his mouth shut, the lawsuit alleges. “Sexually oriented merchandise sold by plaintiff Gina Goldring in a part-time job with a company called Passion Parties were removed from plaintiff’s bedroom and placed in plain view in the 5-year-old’s bedroom,” the suit states.

In allegedly wreaking havoc on the Hollis home, the officers also crushed electronic tablets, stepped on toy train sets, poured out cereal, broke a “muffin maker,” dumped cinnamon spice on the kitchen counter, pulverized a night-light and left out frozen steaks and fish to rot, the suit says.

The cops allegedly swiped $680 in cash — all while snipping cable wires and stomping an Xbox.

The damage occurred after James, a barber, shot their 14-year-old son that May while moving three unregistered firearms from a closet to a garage, according to the suit.

The distraught dad was ready to talk to investigators — but his wife, who was with their wounded son at Long Island Jewish Hospital, told him by phone not to say anything, the suit states.

Annoyed officers informed the husband that he had chosen poorly, the court papers say.

“So you’re lawyered up?” they asked him, according to the suit. “All bets are off. We’re tossing your house and arresting your wife.”

James Goldring was eventually charged with endangering the welfare of a child and served 30 days of community service, according to court papers. Gina Goldring pleaded guilty to disorderly conduct.

The couple said in their suit that the cops’ harassment of them didn’t even stop after the ransacking of their home.

They busted James’ barber-shop customers for loitering and cited him for not sweeping up hair and having uncovered garbage cans, the suit states. With customers scared off, Goldring said he was forced to close in June.

Goldring declined to comment on Friday. His lawyer, Alan Levine, didn’t return a phone call. They are seeking unspecified damages. The city Law Department said it hadn’t been served with the papers.
