MOSCOW, April 20 - RAPSI. The Investigative Committee maintains that Domodedovo Airport Commercial Agency employees were engaged in $7.6 million air fuel fraud, spokesman Vladimir Markin told journalists on Friday.

The fraud was established while investigating airport security violations that allowed a terrorist to detonate a bomb killing 37 people in early 2011. Earlier that day, the security violations case was reportedly dropped as the suspects' conduct did not constitute a crime.

"According to investigators, the employees were aware of the Krasnoyarsk Airlines bankruptcy proceedings and a Vlukovo airport guarantee and faked fuel supply invoices amounting to 224 million rubles ($7.6 million). They then went to court seeking to collect the amount from Vnukovo. Later, the funds remitted to the agency account were stolen," Markin said.

He added that the investigators have also separated from the airport security case evidence that Domodedovo administration officials sold federally-owned land plots within the airport area to offshore companies between 2006 and 2011.
