MOSCOW-A Russian activist used a drone to get his data out of his high-rise flat when police came to search it.

Sergey Boyko says he sent hard drives to a friend by drone when police banged at his door at 10:00 local time, to avoid them getting hold of the data.

The search was part of a nationwide crackdown on the opposition.

Around 200 raids have been carried out in the past few days after the ruling party suffered major losses in local elections in Moscow.

A YouTube video taken (in Russian) by a female companion shows Mr Boyko, who lives in the Siberian city of Novosibirsk, releasing a drone from his flat in a tall apartment block as police wait to be let in.

Boyko heads the local branch of the movement of opposition leader Alexei Navalny, who campaigned for voters to defeat candidates of the United Russia party using tactical voting in Sunday’s city council election.

The activists say the raids are a form of revenge by the authorities for the setbacks.

‘Evacuation’

Boyko’s companion says the couple were woken by loud banging on the door, to find men in civilian clothes and masks demanding to be let in.
