Andrei Kozlov, 41, the first deputy chairman of the Central Bank of Russia, who oversaw bank licensing and led efforts to close down dozens of banks for violations of banking legislation, particularly on money laundering, died September 14 after being shot the day before.
The Prosecutor General's Office claims that starting October 10, some media sources began publishing materials on the course of the probe into Kozlov's murder, which are considered to be state secrets and should be available only to people involved in the investigation.
"A special inspection established that starting October 10, some media agencies began publishing materials on the course of the investigation into this crime, which contain state secrets," the Prosecutor General's Office said. "Media obtained this information, particularly on tactics, operations and searches, from sources connected to the criminal investigation."
The Prosecutor General's Office said it has been taking measures to establish those responsible.
Some Russian media sources reported that three people suspected of killing the Central Bank official have been detained. It was also reported that the suspects were detained after law enforcement officers checked a billing list of all calls made from cell phones near the crime scene at the time of the murder.
Sources involved in the investigation did not reveal any further information, claiming that the detained suspects were only the perpetrators of the crime, and that the investigation was after those who actually ordered the murder.
Last week, First Deputy Prosecutor General Alexander Buksman said the investigation had identified those responsible for the crime and the motive behind the murder. But he refrained from giving any further information or specifying the reason for the killing.
