Relatives say security forces severely beat a member of a banned Islamic group while arresting him in southern Kyrgyzstan.
Members of Dilyar Jumabaev's family told RFE/RL that security forces attacked the Hizb ut-Tahrir member after he refused to allow them to enter his house and demanded a search warrant.
They said he lost several teeth and suffered an open head injury.
Police declined to comment.
Jumabaev is in custody in the regional capital, Osh.
He does not conceal his membership in Hizb ut-Tahrir, a London-based Sunni political organization that seeks to unite all Muslim countries into an Islamic caliphate.
The Kyrgyz government has banned the group, branding its members and supporters "extremists."
Hizb ut-Tahrir is also banned in other former Soviet republics in Central Asia, and in Russia.
