Russian authorities have detained a man suspected of being involved in the deadly school siege in the southern town of Beslan.

Officials in Moscow Wednesday said the man was arrested by security forces in Ingushetia, near the North Ossetia region where the attack took place.

They say there is also information the man took part in an armed attack targeting police facilities in Ingushetia last June.

Militants attacked one of Beslan's schools last September, seizing more than 1,000 children, parents and teachers. 

The ordeal ended in a chaotic outburst of gunfire and explosions that killed more than 330 people, about half of them children.
