A Brooklyn couple is suing an NYPD cop cousin, alleging he harassed and intimidated them for months.

In a Brooklyn federal-court suit filed Tuesday, Lori and Steven Dejesus say Lori’s cousin, Officer Edwyn Stuart, and more than a dozen of his colleagues in the 75th Precinct in Brooklyn waged a battle against them as part of a simmering family feud.

The middle-aged Dejesuses allege that Stuart — unhappy when Lori had his sister arrested for violating an order of protection she had against her — repeatedly arranged for cops to enter the couple’s home under false pretenses.

Stuart was unable to be reached. The NYPD did not respond to a request for comment.
