Honore E. M'Biye, a 39-year-old Zairian native, who moved into a World Bank office here earlier this year posing as a United Nations consultant, was sentenced in U.S. District Court yesterday to one year in prison after being convicted of making false statements on pesonal loan applications to three local banks.

M'Biye, who prosecuters described in court records as a "smooth talking and skillful con man," obtained $6,000 in loans by claiming he worked for the United Nations, the government charged.

The U.S. Atorney's office said in court records that M'Biye "used his knowledge of international organizations to prey upon and take advantage of the courtesies extended to him by the World Bank" and then used his status there to obtain financial credit.

M'Biye was convicted in September of three counts of making false statements in bank loan applications. Judge June L. Green yesterday sentenced M'Biye to serve concurrent terms of one year in jail on each of the three charges. M'Biye, who is being held on a $5,000 bond pending appeal, is subject to possible deportation because he is not gainfully employed, a law enforcement source said.
