A man convicted of getting U.S. citizenship fraudulently after prosecutors said he failed to disclose he was a guard at a concentration camp during the Bosnian War has been sentenced to serve nearly five years in federal prison.

Mladen Mitrovic was found guilty in May of giving false answers on his naturalization application form. Mitrovic said on that application in 2002 that he hadn't ever persecuted anyone because of race, religion or national origin.

Prosecutors said he beat prisoners at the camp.

U.S. District Judge Amy Totenberg on Friday sentenced Mitrovic to serve four years and nine months in prison. She also granted prosecutors' request to revoke his citizenship and said he would likely be deported after he serves his prison sentence.

Mitrovic's attorneys have said they'll appeal.
