MOSCOW. Feb 17 (Interfax) - All of the people accused of helping arrange the January 24 explosion at Moscow's Domodedovo Airport have already been convoyed to the Russian capital, except for Bashir Khamkhoyev, who is suspected of acting as a messenger for North Caucasus militant leader Doku Umarov, a source in law enforcement services told Interfax on Thursday.
"The suspected accomplices of Magomed Yevloyev, who committed the terrorist attack at Domodedovo, were convoyed to Moscow, where investigators have already started to work with them," the source said.
Khamkhoyev is still being held in a jail in the North Caucasus, he said.
Doku Umarov has been accused of masterminding the Domodedovo Airport bombing.
However, lawyers for suspects Umar Aushev and Akhmed Yevloyev have said they know nothing about the decision to convoy their clients to Moscow.
"I have no information that my client Umar Aushev has been convoyed to Moscow as part of the investigation," Aushev's lawyer Umar Khayauri told Interfax.
On Wednesday, Aushev visited the Russian Federal Security Service's branch for Ingushetia, where "he answered investigators' questions in the presence of his lawyer and was then returned to the jail in Vladikavkaz," he said.
Yevloyev's lawyer Visit Kostoyev told Interfax that he had not been informed about measures to convoy his client to Moscow, either.
The explosion at Domodedovo Airport occurred at the international arrivals section on January 24. The bomb with a power equivalent to about five kilograms of TNT, filled with metal parts and attached to the suicide bomber's body, blew up. As a result 36 people were killed and more than 100 injured.
The Russian Investigative Committee opened a criminal case on charges of terrorist attack, murder and arms trafficking.
The Domodevo terrorist attack perpetrator was Yevloyev, a native of Ingush village of Ali-Yurt.
A court in Ingush capital Magas ordered to arrest Akhmed and Fatima Yevloyev, the terrorist's siblings, on suspicion of their assistance to the suicide bomber.
The court in Magas also arrested Umar Aushev, who lives in the same village as the bomber, suspecting him of taking Yevloyev from the village to Nazran two days before the Domodedovo attack.
The fourth arrestee is Ingush resident Khamkhoyev, who, as investigators believe, is one of the gang leaders in Ingushetia's Sunzha district.
