MOSCOW, February 24 (RAPSI) – The Moscow City Court on Wednesday refused to release former director of Domodedovo Airport Vyacheslav Nekrasov and Managing Director of Domodedovo Airport Aviation Security Andrei Danilov, who stand charged with the provision of services that allegedly do not meet security standards in connection with 2011 terrorist attack that left 37 dead, on 5 million-ruble ($65,000) bail, RAPSI learnt in the court’s press office.

Nekrasov and Danilov will remain in detention until February. However, earlier the court changed a measure of restraint of the third defendant, Svetlana Trishina, to the house arrest.

According to investigators, the defendants have not provided sufficient security level that let the suicide bomber freely enter the arrival lounge and set off an explosive.

On January 24, 2011, a suicide bomber detonated a bomb in the Domodedovo Airport’s international arrivals hall, killing 37 people and injuring 172. Doku Umarov, Russia’s most wanted terrorist at the time, claimed responsibility for the attack. Altogether, 28 men connected with the terrorist organization called the Caucasus Emirate were linked to the attack, according to the investigators. Seventeen of them were killed in special operations in 2011, and four were detained.

In November 2013, a Moscow Region court sentenced three men to life in prison and a fourth man to 10 years for their role in the suicide bombing.
