A city cop is accused of repeatedly molesting a young girl over the past five years.

Housing Officer Mackenson Jacques allegedly began sexually assaulting the girl, described as a relative, when she was 10.

The attacks continued regularly until last spring, when the victim, now 15, told her mother, according to Internal Affairs investigators.

Jacques, 29, is expected to be arraigned on rape, sexual-abuse and other charges, according to the Brooklyn District Attorney’s Office.

He has been suspended without pay.
