"Romanov has been detained for interrogation," the message says.
It is noted that investigative measures are being carried out in the Sredneuralsky monastery.
According to the interlocutor of TASS, the reason for the arrest was a video in which Sergius calls on his devotees to "die for Russia."
On October 19, Patriarch Kirill of Moscow and All Russia approved the decision to excommunicate Sergius from the church.
