A second suspect has been arrested on charges of embezzling millions of dollars from Russian's MiG aircraft manufacturer.
Sergei Mamaev, MiG's former deputy director general for economy and finance, was detained by police in April, Russia's Kommersant newspaper reported Wednesday.
The first suspect to be arrested in the case, former Roskosmos quality control director Vladimir Evdokimov, was killed in pre-trial detention a month earlier.
Evdokimov, who had worked at Russia's
United Aircraft Corporation between 2014 and 2015, was accused of
embezzling 200 million rubles ($3.1 million) from MiG.
The 52-year-old was jailed in December, but discovered dead on in his cell on March 18. The cell, which he shared with 11 other inmates, was not covered by CCTV cameras, Russian news outlet Lenta.ru reported.
Evdokimov died with two stab wounds to the heart and one to the neck, police said. Investigators are now treating the death as a possible contract killing.
Mamayev is now set to remain in jail until May 30. His lawyers have confirmed that they will appeal the decision.
