Russia has arrested two more top figures — the deputy head of the army’s general staff and a senior procurement official at the defense ministry — in a widening bribery scandal, investigators said on Thursday.

The arrests of Lt. Gen. Vadim Shamarin and ministry official Vladimir Verteletsky raised the number of detained military and defense officials to five in the space of a month.

Three other men, including a former construction company boss suspected of paying bribes, have also been arrested, signalling a major effort to stamp out corruption surrounding the awarding of lucrative military contracts at a time when Russian forces are fighting in Ukraine.

Shamarin is accused of taking bribes between 2016 and 2023 from a factory in the Ural mountains that produces communications equipment, as a reward for placing bigger state contracts with it, Russia’s Investigative Committee said. It said he had benefited to the tune of at least $400,000.

Shamarin, whose home was reportedly searched in connection with the investigation and who has been placed in pre-trial detention for two months, faces a prison term of up to 15 years if found guilty. State news agency TASS said he pleaded not guilty.

Shamarin has been in charge since 2020 of overseeing the army’s signal corps, which is responsible for military communications, including ensuring confidential battlefield command signals.

Investigators said in a statement that Verteletsky, the senior procurement official, had been charged with abuse of authority in the execution of a state defense order. It said that in 2022 he had signed off on incomplete work that resulted in a loss to the state of over $764,000. It was yet clear how he pleaded.

The clampdown on high-level corruption began on April 23 when Deputy Defense Minister Timur Ivanov was placed in pre-trial detention for suspected bribe-taking.

Since then, Lieutenant-General Yuri Kuznetsov, head of personnel at the defense ministry, and Major-General Ivan Popov, former commander of Russia’s 58th army, have also been arrested.

The arrests are the biggest scandal to hit the Russian army in years and come at a time when it is has regained the initiative on the battlefield in Ukraine and has a new defense minister, economist Andrei Belousov, at its helm.

The appointment of Belousov, who has no army experience, was widely seen, among other things, as a move to eliminate wastage and corruption in defense spending. Sergei Shoigu, the previous minister, has been moved to become secretary of Russia’s Security Council.

The Kremlin, which said it was not authorised to disclose details of the case, played down Shamarin’s arrest and said similar anti-corruption work was being carried out across various Russian state agencies.

“The fight against corruption is consistent work,” Kremlin spokesman Dmitry Peskov told reporters. “It is not a campaign, it is constantly ongoing work.”

Anti-corruption drive

Sergei Markov, a former Kremlin adviser, said Shamarin’s arrest was the continuation of a sweeping shake-up among the army’s top generals.

“The arrest of Shamarin, deputy chief of the General Staff, is not only an arrest, but also a large-scale audit of the work of the Main Communications (Signals) Directorate by the Audit Chamber,” Markov said.

He said one of the probe’s aims was to “increase the army’s morale and equip the army with modern communications equipment and missile and artillery guidance systems”.

An influential military blogger close to the defense ministry who goes by the name “Rybar” and has over 1 million followers, said the arrest and others like it were logical, but that investigators had probably sat on the alleged wrongdoing for a long time before acting.

Shamarin is a deputy to Valery Gerasimov, chief of the General Staff, who is managing the war in Ukraine. Gerasimov has not been accused of any wrongdoing, though he has at times faced harsh criticism over the performance of Russia’s military since its full-scale invasion of Ukraine in February 2022, something Moscow calls a special military operation.
