A private house of the head of the local criminal investigations unit of the Malgobek interior department Isa Korigov came under attack in Ingushetia in the early hours of Thursday, Itar-Tass reported. A source at Ingushetia's Interior Ministry said that the police chief hadn't been hurt in the fire attack and the building was slightly damaged. A makeshift explosive device went off twenty minutes after the fire attack when an investigative group had arrived at the scene and neighbors had come out into the street. Five people were wounded in the blast, including Isa Korigov.
