Andrey Botikov, a top scientist, was found dead in his Moscow apartment on Friday.
His death which was considered suspicious is being looked into by Russia’s investigative committee.
Botikov, known as one of the 18 scientists who worked on the Sputnik V coronavirus vaccine in 2020, was identified as the man who had been strangled to death with a belt in northwest Moscow.
It was previously reported he had survived the encounter after an intruder broke into his home and started rowing with him over money.
But a 29-year-old man has since been arrested and charged with the murder of the scientist.
The Investigative Committee of Russia said they found the suspect in ‘the shortest possible time’ after he tried to flee the scene.
They claim he confessed to the crime during an interrogation.
The committee also reported the defendant had already been prosecuted for committing another ‘serious’ crime.
Russian media reported that the suspect, known as Alexei Z, had spent 10 years in prison on charges of providing s3x services.
Andrey Botikov was a senior researcher at the National Research Center for Epidemiology and Microbiology.
He had previously worked at the Russian State Collection of Viruses D.I. Ivanovsky Institute of Virology as a senior scientist.
He was awarded an Order of Merit for the Fatherland for his work on the Sputnik V vaccine.
Sputnik was the first registered combination vector vaccine against Covid-19.
