Eleven people are still being treated at hospitals after sustaining injuries in a grenade explosion outside a cafe in the town of Tugulym in Russia's Urals region, local Health Ministry spokesman Konstantin Shestakov told Interfax on Tuesday.
Sixteen people were rushed to hospitals after a grenade was detonated outside a cafe in the center of Tugulym early on March 9, he said.
Two local residents have already been detained for their suspected involvement in the crime.
Regional investigators believe that an RGD-5 offensive grenade was detonated in Tugulym. They are tentatively investigating the incident as an act of hooliganism or a conflict between persons under the influence of alcohol.
Sverdlovsk region police spokesman Valery Gorelykh told Interfax on Monday that two Tugulym residents had been detained following the explosion.
"The police operation was carried out in two stages. First, the detectives tracked down a young man named Anton, who was detained in Talitsa. His acquaintance, known by his nickname Klim, who has a previous criminal record, was detained at one of the apartments in Yekaterinburg. They had no time to offer any resistance to police. Both suspects were taken by surprise by policemen\'s rapid measures to track them down," he said.
The young men have already been transported to Tugulym. Investigators are currently working with them.
