The questioning lasted for three hours, according to MBKh Media portal.
Russian nationals Orkhan Dzhemal, Kyrill Radchenko, and Alexander Rastorguev were killed in CAR on July 30. The committee opened a criminal investigation. According to the Russian Foreign Ministry, preliminary information showed that robbery was the motive behind the armed attack.
The killing of the three journalists has become a high-profile case both inside and outside Russia.
CAR has recently been suffering from numerous internal conflicts. Between 2012 and 2014, the country faced a civil war involving the government, an alliance of rebel groups called Seleka, predominantly composed of Muslims, and Anti-Balaka militias, whose members were mostly Christians. The violence did not stop even after Seleka was dissolved in 2013.
The Russian Foreign Ministry has said that the criminality level amid the turmoil in CAR was high and warned people visiting the country that they should not rely on help from local law enforcement, which was practically defunct.
