Outspoken Kremlin critic Aleksei Navalny, who is under house arrest in Moscow, has been fitted with an electronic tracking device.
A spokeswoman for the Federal Service of Correctional Institutions said on March 4 that Navalny was ordered to wear the device on March 3 after he had finished serving a seven-day jail term for disobeying police during an unsanctioned gathering in Moscow.
On February 28, a court in Moscow ordered that Navalny be put under pretrial house arrest until April 28 while a probe continues against him and his brother Oleg in a case linked to alleged embezzlement and money laundering.
Navalny was also barred from using the Internet or talking to the media.
Navalny, an anticorruption blogger and opponent of President Vladimir Putin, is serving a five-year suspended sentence on a theft conviction he says was a Kremlin reprisal.
