The court in Mayluu-Suu on August 2 found Mamatkadyr Karabaev guilty of fraud and falsification of official documents.
Karabaev denies the charges, which he says are fabricated.
Karabaev was arrested on June 6, shortly after participating in a rally to demand that Uzbek be given the status of an official language in Kyrgyzstan. He says that was the real reason for his arrest.
Ethnic Uzbeks represent the largest population group in some of Kyrgyzstan's southern areas.
