New evidence suggests Putin has freed violent offenders to boost troop numbers in Ukraine.
Vadim Tekhov, 33, was sentenced to 16 years in prison last year for the brutal murder of his ex-wife, Regina Gagieva.
But footage of him being detained by police in November 2022 has brought to light reports that he had been released early to fight with a ‘special regiment’ of the Defence Ministry in Ukraine.
Tekhov, a former policeman, confronted the mother of his child in a shop in Vladikavkaz, Russia, over alleged text conversations with other men.
When Ms Gagieva refused to unlock her phone for him, Tekhov stabbed her several times across the neck and upper body.
Gagieva died in hospital, and Tekhov was jailed after it emerged his ex-wife had approached the authorities several times with domestic abuse allegations.
The story was widely reported in Russia last year, causing public outcry.
