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.
