Investigators have brought murder charges against the teenager who shot and killed a teacher and a police officer at Moscow school N263 last week, Russian Investigative Committee spokesman Vladimir Markin said.

"He has been charged with killing two persons while they were on duty, attempted murder and hostage taking (articles 105, 206 of the Russian Criminal Code)," Markin told Interfax on Wednesday.

The accused is due to undergo psychological and psychiatric forensic tests, he said.

The hostage taking by a high-school student armed with two rifles at Moscow school N263 on February 3 resulted in the death of geography teacher Andrei Kirillov and policeman Sergei Bushuyev. Yet another police officer, senior sergeant Vladimir Krokhin, was injured and hospitalized in serious condition.

The teenager was apprehended and had a criminal case launched against him under three articles of the Russian Criminal Code: 206 (hostage taking), 105 (homicide) and 317 (an attempt on the life of a law enforcement officer). Moscow's Basmanny Court remanded him into custody until April 3.
