Russia has not encouraged LGBT rights in the past and an non-governmental group, the Russian LGBT Network, said in a post on Facebook that he was detained on Saturday at an LGBT community centre in the Volga River city of Samara.
His lawyer, Karina Artyunyan, said a city court ruled that Mr Mulcahy had violated the terms of his tourist visa by engaging in religious activities.
The West has criticised Russia in the past for laws that restrict the rights of minority religious groups as well as people in the country who identify as gay or lesbian.
