The HACC chose a preventive measure for another figure in the NABU and SAP operation "Carthage" former First Deputy Head of the Department for the Protection of National Statehood of the SBU, Serhiy Duka ("Akim"). The investigating judge sent the suspect into custody with an alternative bail of 65 million UAH. The session was accompanied by many procedural disputes due to the closure of the process, an SBU letter about a terrorist threat, recusals, as well as details of the search of Duka's house and the presence of "Alpha" fighters there.

From the very beginning of the consideration of the motion, Judge Volodymyr Voronko changed the courtroom, limiting access to listeners and journalists due to lack of space, and did not consider the motion for online broadcasting of the session. Initially, the defense unsuccessfully tried to recuse SAP prosecutor Mykola Karas, and later requested to close the process to preserve Duka's personal data and due to the SBU letter about a possible terrorist attack. The judge decided to hear the prosecution in closed session, and the defense in open session. Prosecutor Karas opposed this decision, as he was not allowed to familiarize himself with the special service's letter, and filed a recusal against Voronko, indicating his possible connections with the lawyer. However, Judge Kravchuk, who considered the recusal motion, left Voronko as the investigating judge in the preventive measure.

According to the prosecutor, Duka is accused of participating in the criminal organization of Andriy Osipov ("Criminal") and the leader of "KhimProm" Yehor Burkin ("Mexican"). According to the investigation, the SBU official advised Osipov on how to cover up the criminal activities of drug shops, negotiated with other law enforcement officers on his behalf, helped lift arrests from cryptocurrency seized during an investigation into "U420" stores through Pechersk District Court, and coordinated the security of fraudulent call centers. In the summer of 2026, he advised closing offices and "guerrilla" in apartments, provided Osipov with departmental passes for traveling through Ukraine and access to the SBU building.

The prosecutor requested a preventive measure for Duka in the form of detention with bail of 100 million UAH. He emphasized the risk of flight, Duka's connections with high-ranking officials of many bodies, fake letters for departure, and Russian passports among his wife's relatives. In court, the prosecutor demonstrated fragments of phones that were allegedly broken by the suspect during a search to hide their content. However, correspondence revealed intentions to falsify materials regarding NABU detective Magamedrasulov. The prosecutor also pointed out that "Alpha" fighters guarding the former official aimed weapons at NABU employees and claimed they had orders to open fire. Meanwhile, Duka was in the house from where detectives heard a gun being cocked.

In court, Serhiy Duka denied guilt, claiming a lack of evidence and the absence of clearly incriminated crimes in the suspicion. Regarding "Alpha," he explained that it is his official state security, tasked precisely with protecting his house from possible intrusion, including by NABU employees. The defense added that anyone could have broken the phones, even children, information about Russian passports was taken from the media and unverified, and Osipov's visits to the SBU are not a crime. The bail of 100 million UAH was deemed excessive by the defense.

Investigating judge Voronko partially supported SAP's motion by applying a preventive measure for Duka in the form of detention with an alternative bail of 65 million UAH. Let us recall that yesterday in the "Carthage" case, the court had already sent the executor of attacks Vitaliy Rybalko ("Boxer") and DSR official Volodymyr Tsenov ("Price") into custody without bail with an alternative bail of 15 million UAH, which has already been posted. Today the official of Kyiv Region National Police Oleksandr Demianchuk ("Consultant") was also sent into custody without bail.
