The elder brother of the prime St Petersburg bombing suspect has been detained just outside Moscow.
Akram Azimov was detained by officers in Odintsovo, according to the media team at Russia's Federal Security Service (FSB).
Azimov is accused of providing money to help his younger brother, Abror Azimov, carry out the attack on a subway train which left 14 people dead.
Abror Azimov told a Moscow court yesterday (April 18) that he had simply "followed instructions" in carrying out the attack on April 3, but had been unaware he was committing a terrorist act.
“I am not appealing the arrest, but what the investigator said about me admitting guilt is inaccurate," news agency Tass quotes Abror as saying.
"I was involved, but not directly. I wasn’t aware of what I was doing, I was given commands and I followed them."
