Arrested on charges of carrying explosives and causing property damage, he was not extradited following a recommendation from the European Court of Human Rights which argued that he would face torture if returned to Russia.

Osmayev has been targeted in assassination attempts allegedly orchestrated by the Russian government on multiple occasions, most notably an October 2017 shooting that killed his wife Amina Okueva.

[2] Adam's uncle Amin Osmayev [ru] was chairman of the pro-Russian Supreme Soviet of the Chechen Republic in 1995 and from 1996 to 1998, concurrently serving as a member of the Federation Council.

[1] According to a report by Kommersant, Osmayev studied under members of the Chechen diaspora at a mosque in the United Kingdom, where he was educated in explosives.

The plot's organiser was claimed by the FSB to be Chingiskhan Gishayev, an associate of Chechen jihadist leader Dokka Umarov.

[2] Following his father's command to move to Ukraine, Osmayev lived in the southern city of Odesa and worked as a consultant at a stock-trading firm.

He befriended fellow Chechen Ruslan Madayev and Kazakh Ilya Pyanzin, and was also allegedly contacted by representatives of Umarov while abroad.

[7] Some Ukrainian media, namely KP and Segodnya, alleged that the publicisation of the investigation was a prelude to the arrests of hired killers who planned an attack on an Odesa businessman.

Osmayev's father was charged with participation in "armed raids and preparations of terrorist attacks," but was released soon after investigators concluded he had simply been visiting his son at the time of the arrest.

Investigators at the time alleged that Osmayev and Pyanzin were involved in an effort to assassinate Putin and other top Russian officials, recruit members of a broader terrorist network, and destabilise Russia.

[6] Pyanzin's effort to avoid extradition, however, was not fulfilled, and he was transferred to Moscow on 24 August 2012, being found guilty and sentenced to ten years' imprisonment in 2013.

A 1 June incident involved Russian national Artur Denisultanov-Kurmakayev, who shot at Osmayev while posing as Le Monde journalist Alex Werner, but was wounded by Okueva.
