The video Russian police 'leaked to scare people'

The arrest and the jailing of Russian opposition leader Alexei Navalny has sparked unprecedented street protests in Russia. With the Kremlin determined to crack down, police have been targeting opposition activists across the country, as far away as Vladivostok, 4,000 miles east of the capital.

An online video shows Vladivostok protester Gennady Shulga in a headlock over his dog's food bowl as Russian police interrogate him in his home. The BBC travelled to meet Shulga, who said he believes the video was leaked to 'show people what the authorities can do'.
