MOSCOW, May 13 (RAPSI, Diana Gutsul) - An investigation into the seizure of hostages in the Dubrovka Theater in southeast Moscow in 2002 that left 130 dead has been completed, attorney Igor Trunov told RAPSI on Wednesday.

Khasan Zakayev, a 41-year-old resident of Chechnya, stands charged with masterminding the terror attack, attempted murder by a group of persons and being a member of a criminal gang.

Zakayev faces life in prison if convicted.

He was arrested while attempting to enter the Republic of Crimea using forged documents.

A group of terrorists led by Movsar Barayev took hostage the audience and participants of the Nord-Ost musical on October 23, 2002.

40 attackers were killed. Zakayev is the only one who was arrested, Trunov said.

The majority of hostages were released in an operation planned by Russian security services.

Chechen separatist leader Shamil Basayev who was reportedly killed in 2006 and Gerikhan Dudayev who is still at large are among the organizers of the attack, according to investigators.
