Moscow condemned the action of the Czech police, calling the detainment a ‘provocation’.

Czech police have detained a Russian cleric after four containers of a suspicious white substance were discovered in his car.
Orthodox Bishop Hilarion was detained in the town of Karlovy Vary, according to a statement released on his Telegram channel by his defence team on Monday.

The arrest sparked claims of provocation from Moscow against Czechia’s government, despite Prague having reduced its support for Ukraine since it took office six months ago.
Bishop Hilarion, 60, whose secular name is Grigory Alfeyev, heads the Russian Orthodox Church’s congregation in the western town, which hosts a sizeable Russian diaspora.
The cleric denied any involvement in drug possession. “I have no connection and have never had any connection to the illegal trafficking of narcotic substances,” he said in the statement.
Czech police said only that a man was detained on Sunday evening on a highway between Karlovy Vary and Prague, adding that interrogations were under way and no one had been charged, without disclosing the detainee’s identity.
The Czech Drug Enforcement Centre said it had also acted on an anonymous tip-off reporting the transport of narcotic and psychotropic substances.
Hilarion’s defence said police offered no clear reason for stopping the vehicle and that two patrol cars appeared to be waiting for it on the road.
Hilarion was not permitted to observe the search, his lawyer said, adding that the defence was demanding independent forensic analysis of the substance along with fingerprint and DNA checks.
‘Provocation’
Russian Foreign Ministry spokeswoman Maria Zakharova called the incident an “orchestrated provocation” aimed at discrediting Hilarion, and demanded his immediate release.
“The head of the Czech diplomatic mission in Moscow will shortly be summoned to the Russian Foreign Ministry, where a strong protest will be lodged regarding the unacceptable high-handedness of the Czech authorities,” she said.
Russian media reported that the detention followed months of anonymous threats against Hilarion, including threats of physical violence demanding he leave his post in Karlovy Vary.
Hilarion was once considered the right-hand man of Patriarch Kirill – the head of the Russian Orthodox Church and a pillar of support for President Vladimir Putin and his war on Ukraine.
However, the priest reportedly fell out of favour with Moscow’s spiritual authorities and was sent abroad in 2022, shortly after Russia’s invasion.
His assignment to the Czech Republic came after a former aide brought sexual misconduct charges against him, allegations Hilarion denied, claiming the aide had attempted to extort €384,000 from him.
Unlike many senior Russian clergymen who have publicly backed the war in Ukraine, Hilarion has never publicly commented on the conflict.
Separately on Monday, the Czech government, a coalition of populist and far-right parties that took office in December, announced that it had approved a legal amendment that would tighten rules for Ukrainian refugees’ stays and financial support. It said it was responding to the abuse of aid, and the perception that refugees had some advantages over locals.
