Putin opponent arrested

Russian opposition leader Alexei Navalny has been arrested after his supporters staged demonstrations against the forthcoming presidential election. In chaotic scenes which were caught on camera, he was bundled into a police van. Earlier police used an angle-grinder to break into his online TV channel and make arrests.
Navalny is barred from standing in the election due a fraud conviction which he contests as politically motivated.

He has long been a critic of President Putin and has called for a boycott of what he says are rigged presidential elections, set to take place in March.
