He described Kusaitė, a young Lithuanian female charged with setting up an organized group for a terrorist attack and attempting to detonate herself in a strategic object in Chechnya, as a fanatic of the Islamic holy war, jihad.
"She was obsessed with the holy war, she wanted to be part of it, (…) she liked hitmen. I learned from Apti that she wouldn't be able to come, as her journey had been interrupted," reads the testimony recorded by Russia's Federal Security Service (FSB).
The defendant's lawyer Kęstutis Stungys objected to the disclosure of the testimony during the Wednesday's hearing. Kusaitė also did not want the testimony to be made public, saying the testimony was not consistent with the testimony made at later hearings of the Magmadov trial in Moscow.
"The main difference is that he denied having told Apti Magmadov that Kusaitė went there to detonate herself, therefore, his presence is necessary," said the lawyer.
Kusaitė requested repeated summoning of Arsigirayev, but the court overruled the motion.
The witness told the FSB agents that he had learnt from Apti Magmadov, a Russian citizen of Chechen nationality who has been recently sentenced, about Kusaitė meeting his sister Aishat Magmadova online.
The Lithuanian woman was planning to marry one of the leaders in a military camp and, according to the testimony, would have been used as a suicide bomber.
The next hearing in the trial is scheduled for 21 March, it should be attended by other witnesses from Russia and former security officers from Lithuania's port city of Klaipėda.
Kusaitė refused to comment on Arsigirayev's testimony to journalists.
