Russian police sources have identified the suspected suicide bomber as Magomed Yevloyev, 20, a native of the North Caucasus republic of Ingushetia.
Russian news agencies report the arrest this week of Yevloyev's 16-year-old brother Akhmed and his 22-year-old sisted Fatima on suspicion of involvement in the attack.
A third alleged accomplice, identified as Umar Aushev, 23, was also arrested.
Chechen Islamist rebel leader Doku Umarov has claimed responsibility for the January 24 bombing at Moscow's Domodedovo airport.
