Russian opposition politician Boris Nadezhdin, a liberal critic of President Vladimir Putin, is briefly detained by police, according to two outlets. Both reports say the detention occurs on Monday and involves law enforcement action that temporarily restricts his freedom of movement.

Nadezhdin is described as a prominent figure in Russia’s political opposition who has publicly opposed Moscow’s actions in Ukraine. The coverage emphasizes that the detention is short and does not present further details such as charges, the location, or the reason for police intervention beyond the brief hold.

Taken together, the reports portray Nadezhdin as a known critic of the Kremlin whose political stance—particularly regarding the war in Ukraine—continues to draw attention from authorities. The sources do not indicate whether the detention is connected to a specific event or planned activity, and they do not provide information about his condition after release.
