A new lawsuit accuses US police officers of unjustly strip-searching a honeymooning Israeli man at a shopping centre and mocking his genitals.

The unidentified 38-year-old man filed a discrimination lawsuit in Bergen County Superior Court, New Jersey, on Wednesday.

The lawsuit says security at the Westfield Garden State Plaza mall stopped the man in November 2015 after he was accused of shoplifting.

When a search of the man's shopping bag uncovered no stolen items, the suit claims at least three Paramus police officers forced him into a corridor "open to the public" and pulled his pants down.

The officers were allegedly "openly laughing" while making fun of the man's genitals, accent and national origin.

The borough's lawyer says he has not seen the lawsuit.
