On Friday, July 4, Kazakhstani media erupted with news of the arrest of Talgat Tatubayev, former head of the National Anti-Corruption Bureau, predecessor to the current Anti-Corruption Agency. Yet the significance of Tatubayev’s arrest may extend far beyond his own record. Many believe the case is the opening move in a broader probe that could ensnare Kairat Kozhamzharov, a former senator and top security official under Kazakhstan’s first president.
Tatubayev’s arrest was amplified by a post from Aset Mataev, head of the KazTAG news agency and the son of Seytkazy Mataev, the current chairman of the Union of Journalists of Kazakhstan. Both father and son were previously prosecuted during Kozhamzharov’s tenure, a period marked by high-profile anti-corruption investigations, including the conviction of former economy minister Kuandyk Bishimbayev.
While Kozhamzharov’s leadership was once praised for exposing major corruption cases, many in Kazakhstan’s media remained skeptical. The elder Mataev’s case in particular shook the journalistic community, which saw his prosecution as politically motivated. It is widely believed that the Mataevs were targeted after refusing to sell KazTAG to allies of then-Mazhilis Speaker Nurlan Nigmatulin.
“In 2016, I had two encounters with Deputy Head of the Financial Police, Talgat Tatubayev,” Aset Mataev wrote on his Telegram channel. “He offered us a deal under Article 65 of the Criminal Code, exemption from liability in exchange for a guilty plea. Others close to Nigmatulin, Yeseyev, Baybek, Zhumagaliyev, and Mailybayev took that route. We refused”.
At the time, the Union of Journalists was gaining influence in the blogosphere amid growing distrust in traditional media. According to Aset Mataev, this created an opportunity for authorities to undermine the Mataevs’ reputation and isolate them professionally. Tatubayev’s damaging interview, published on Ratel.kz, appeared to many as a tool in this campaign.
“He tried to intimidate us, saying, ‘We have orders, and we’ll crush you anyway,’” Mataev wrote. After Seytkazy’s arrest, Tatubayev allegedly contacted Aset from his father’s phone, urging him to stop speaking to the press. “He promised the case would be dropped. Of course, he lied. We were tortured until the verdict was handed down, while he gave interviews claiming my father admitted guilt.”
Unlike Ratel.kz, which was seen as aligned with certain state actors, other outlets mentioned by Mataev allegedly served figures like Bulat Utemuratov, long considered the financial backer of former President Nursultan Nazarbayev, and Karim Massimov, who moved from prime minister to head of the National Security Committee in 2016.
The Mataev prosecution sparked widespread condemnation among journalists, who viewed it as a watershed moment in Kazakhstan’s clampdown on press freedom.
To this day, the Mataev case is widely believed to have been orchestrated by Nigmatulin and his political allies.
Now, with Tatubayev under arrest once more, this time for alleged torture in the notorious Khorgos customs embezzlement case, some observers see the return of unfinished business from the “Old Kazakhstan.” Khorgos, a major border post linking Kazakhstan and China, was the center of large-scale corruption investigations under Kozhamzharov’s leadership.
The General Prosecutor’s Office confirmed Tatubayev’s detention in relation to abuses during the Khorgos probe. Meanwhile, rumors are circulating that Olesya Keksell, one of the key investigators in the Bishimbayev and EXPO-2017 cases, has also been named a suspect.
Whether these developments mark a genuine reckoning or a narrative driven by Kozhamzharov’s critics remains to be seen. If the allegations prove true, the investigation could expose a deep web of corruption tied to the former regime, a legacy Kazakhstan is still grappling with.
