Server Karametov, a Crimean Tatar, was last night sentenced to 10 days' "administrative detention" for picketing in support of prisoner of conscience Akhtem Choygoz and others outside the Supreme Court of Crimea operating under control of the de-facto authorities in the occupied region's capital Simferopol, according to Amnesty International.
"Arresting a frail senior citizen and throwing him behind bars for holding a placard is the latest grotesque example of the Russian authorities' incessant crackdown on peaceful activism by the Crimean Tatar community," said Oksana Pokalchuk, Executive Director of Amnesty International Ukraine.
"This case epitomizes the ongoing, brutal persecution of Crimean Tatar activists. Server Karametov should be released immediately and unconditionally."

Late on August 9, a judge from the Zheleznodorozhny District Court of Simferopol found Server Karametov guilty of resisting "lawful orders" from police officers.
In addition to his detention, he was fined 10,000 rubles (US$165), an extortionately high amount for someone from Crimea where the average monthly retirement benefit is slightly above 11.000 rubles (US$180).
Karametov felt ill in the court room and an ambulance had to be called. His lawyer said the activist suffers from Parkinson's disease and may be deprived of his essential medication while in detention.
Akhtem Chiygoz, who was named on the placard, is the deputy leader of the Crimean Tatar representative body Mejlis, which is banned in Russia as an "extremist" organization.
He has been detained since January 2015 on trumped-up charges of organizing "mass disturbances" on February 26, 2014, during a protest that took place shortly before the Russian occupation and annexation of Crimea.
"With Mejlis banned as 'extremist', its leaders imprisoned or forcibly exiled from their homeland and Crimean Tatar-language media purged from Crimea, how much further can these reprisals go?" said Pokalchuk.
"These deplorable repressions are the daily reality in Crimea."
