Police seized a painting of Russia's president and prime minister in women's underwear from a gallery in St Petersburg, saying the satirical display had broken unspecified laws.
The officers also removed a picture of the head of the Russian Orthodox Church, his torso covered in tattoos, and two others poking fun at lawmakers who have backed legislation banning so-called gay propaganda, gallery staff said.
The police service said it had taken paintings from the "Museum of Power" gallery - based in two rooms of a flat - late on Monday after receiving reports they were illegal.
It gave no further detail but Russia does have a law against insulting authorities - an offence that carries a maximum one-year prison term.
One painting showed president Vladimir Putin wearing a tight-fitting slip and brushing the hair of Prime Minister Dmitry Medvedev, who is wearing knickers and a bra.
St Petersburg deputy Vitaly Mironov, whose face was combined with the gay rights movement's rainbow flag in one of the paintings, told Reuters the images were inappropriate and "of a distinctly pornographic character".
St Petersburg, which next week hosts world leaders at a G20 summit, was one of the first Russian cities to introduce a law banning the spread of "gay propaganda".
The Russian parliament has also adopted similar legislation, prompting protests from abroad and calls for a boycott of the Winter Olympics which Russia will host in the Black Sea resort of Sochi in February.
Gallery owner Alexander Donskoy said the officers had also shut down his establishment and have him no explanation for the removal of paintings from the exhibition, titled 'Leaders'.
"This is an (illegal) seizure," he told Reuters. "We have been given no formal documents banning us from operating and no receipt confirming our petty cash was seized."
据路透社报道，俄罗斯警方日前在圣彼得堡一家博物馆没收了几件展品，其中包括酷似普京和梅得韦杰夫的画像。
据警方透露，在收到举报后，他们于8月26日晚从“权力博物馆”的画廊收走了这些画作。
其中一幅题为“滑稽”的作品恶搞俄罗斯总统普京和总理梅德韦杰夫，一向以强人形象示人的普京总统在画面上身穿紧身吊带内衣，正在为身穿女士内裤和胸罩的梅得韦杰夫梳头。
圣彼得堡议员维塔利·米罗诺夫也成为画家描绘的对象，只是脸上被画上同性恋权力运动的彩虹旗。米罗诺夫不满地说，这些肖像不合适，“显然具有淫秽性质”。
俄罗斯法律禁止侮辱政府官员，违者可判有期徒刑一年。
画廊主人亚历山大·东斯科伊说，警方没有向他解释查没这些绘画的原因。
将于下周主办G20峰会的圣彼得堡是俄罗斯第一个颁布法律禁止传播“同性恋宣传”的城市。俄罗斯议会也通过了类似法规，因而引发国外抗议。有人还呼吁联合抵制俄罗斯明年2月在黑海度假胜地索契主办的冬季奥运会。
