Russian police arrest protesters demanding Navalny's release

More than 4,000 people, including Alexei Navalny’s wife, Yulia Navalnaya, were detained at rallies across Russia as supporters of the Kremlin critic took to the streets to protest against his imprisonment. Security measures, riot police and national guards troops shut down metro stations in Moscow and blocked off streets to prevent a repeat of last week’s record protests, some of the largest since 2012.
