A Moscow court has ruled to free Dmitry Kamenshchik, the owner of the Domodedovo airport, from house arrest, Russian news agencies report.
Based on the July 1 ruling by Moscow City Court, the house arrest of two of Kamenshchik’s associates will also be lifted.
The probe against Kamenshchik and others was launched after relatives of victims of a 2011 terrorist attack at the Domodedovo airport filed lawsuits demanding financial compensation.
Kamenshchik and his associates are facing charges linked with security measures at the airport at the time of the attack.
They have rejected the charges.
More than 30 people were killed and 172 injured in the suicide bombing at Domodedovo airport in January 2011 as a bomber blew himself up in the airport's arrival zone.
