An investigator phoned Syarhey Vysotski, former leader of the unregistered Belarusian Freedom Party, and asked him to report to the Investigative Department on July 23.

The investigator did not mention any reasons, noting only that Vysotski does not need a lawyer to be present at the meeting that would last just 10 to 15 minutes, RFE/RL Belarus Service reported.

Vysotski was released on July 12 after spending two days in the KGB pretrial detention center in connection with the July 4 Independence Day concert bombing.
