MOSCOW, May 22 - RAPSI. Investigators have interrogated the Pussy Riot punk gang as witnesses in the case against Andrei Borodin, who attacked the judge handling their case with an ax, their lawyer Mark Feigyn told the Russian Legal Information Agency (RAPSI/

"The investigators have questioned our clients today, but they did not provide any important information," he said.

"Investigators were largely concerned with whether the women know Borodin personally or have any relations with him. They explained that they have neither heard of him nor had any relations with him."

Feigyn added that Borodin has undergone a psychological examination, but the results are still unknown.

On April 24, the Moscow Khamovnichesky District Court sanctioned the arrest of Borodin, 36, who allegedly burst into a Tagansky District Court judge's office wielding an ax and demanding the release of the Pussy Riot punk group members.

The judge resisted the attack and called for help.

The bailiffs soon detained Borodin.

On February 21, five masked members of the Pussy Riot punk-group performed a protest song called "Holy Sh*t" at the altar of the cathedral. The video of their performance was posted on the Internet and incited a major public uproar.

Three suspected Pussy Riot members are now under detention, facing up to seven years in prison for hooliganism. The court ruled to keep Nadezhda Tolokonnikova, Maria Alyokhina and Yekaterina Samutsevich in detention until June 24.
