Eleven Nigerian police officers found responsible for sexual misconduct while serving in a United Nations peacekeeping force in Congo have been suspended, Nigeria's police chief said Monday. Among those who breached U.N. rules on sexual misconduct was the head of the contingent, Chief Superintendent of Police Anthony Okon, according to the statement Monday from the police chief, Sunday Ehindero. Okon and 10 others from the 120-member team, which was recalled to Nigeria earlier this month, have been suspended from the force, it said. No details of the allegations against them were given. "No member of this contingent will ever go on a peace mission or other assignments outside this country," Ehindero said.
