Russia has opened a criminal case against a police officer accused of leaking data that could have helped identify the alleged poisoners of Kremlin critic Alexei Navalny, the RBC business daily reported on Tuesday, citing sources. The information leaked, according to RBC, is thought to relate to flights taken by agents from the FSB security service with specialised knowledge on chemical weapons identified in an investigation as having secretly followed Navalny for several years. "Investigators are not looking for or imprisoning Navalny's poisoners, but those who disclosed their data," Georgy Alburov, an ally of Navalny, wrote on Twitter.
