Russian police detained over 140 people including a high-profile Moscow deputy after Kremlin critics protested Wednesday against changes to the constitution.

The group, which tracks arrests at political protests, said 142 people were detained Wednesday evening. Many people including journalists were put in police vehicles.

A vote earlier this month amended Russia’s constitution, handing Putin the right to run for two more presidential terms, an outcome the Kremlin described as a triumph.

Opposition activists say the vote was illegitimate and that it is time for Putin, who has ruled Russia for over two decades as president or prime minister, to step down.
