United Nations ( CNN ) -- Three Pakistani police officers were found guilty of sexual exploitation and abuse of a 14-year-old Haitian boy while they were serving in a U.N. police mission in Haiti , a U.N. spokesman told reporters Tuesday . The three were found guilty in a court-martial proceeding conducted by Pakistani authorities in Port-au-Prince , Haiti , said the spokesman , Martin Nesirky . Pakistani authorities alerted Haitian officials to the outcome of the military procedure this month , saying that `` the guilty parties will be punished , including dishonorable discharge from service , loss of benefits and imprisonment , with the latter sentence to be served immediately on return to Pakistan . '' Each is to serve a year in jail . The three were in a Pakistani-formed police unit serving in Gonaives , Haiti , as part of the United Nations Stabilization Mission in Haiti in the wake of the devastating earthquake there in January 2010 . The attack happened this January . The three officers have been sent back to Pakistan . The U.N. spokesman said the international body is in contact with Pakistani authorities to `` examine the formal details of the procedures and to ensure appropriate follow-up . '' Asked by a reporter if the one-year sentence was appropriate for the crime , Nesirky responded , `` The United Nations will not comment on the terms of the punishment under the member-states , the judicial procedure . That 's obviously a matter between Pakistan and Haiti , but as we stated from the outset , the United Nations considers this to be a case of the most serious sexual exploitation and abuse . '' In a separate case , five Uruguayan marines were accused last year of sexually assaulting a teenager at a U.N. base after a video was posted on the Internet . That case is still under investigation .
A court-martial was held by Pakistani authorities in Haiti . The three police officers are to be imprisoned for a year in Pakistan . The United Nations announces the court-martial results .
