Authorities have detained a suspect they believe may have taken part in the deadly hostage-taking raid on a school in the southern Russian town of Beslan last September, the Interfax news agency reported. The suspect was detained by police and security officers in Ingushetia, adjacent to North Ossetia, the region where the attack took place, Interfax reported, citing an unnamed source in the headquarters of Russia's campaign against militants in Chechnya and surrounding areas.The source said there also was information indicating the detainee took part in a large-scale attack last June targeting police facilities in Ingushetia, the agency reported. Assailants attacked School No. 1 in Beslan on the first day of school, Sept. 1, seizing more than 1,000 children, parents and teachers as hostages. The ordeal ended in a chaotic outburst of explosions and gunfire that killed more than 330 captives, more than half of them children. Russian officials have said that 32 attackers took part, and that 31 of them were killed and one captured. Media reports have suggested there were more attackers and that some escaped.
