MOSCOW, August 29 (RAPSI) – A new bill which is expected to reach the Russian government by September 20 is designed to toughen the federal gun law, RIA Novosti reported Thursday.

The bill imposes tough restrictions on those who have alcohol addiction or problems with mental health, nervous system. Such people will undergo thorough examination if they apply for a gun ownership license.

The initiative was triggered by a series of incidents which took place in 2012 and 2013.

In November 2012 after a five-day drinking binge, Dmitry Vinogradov opened fire at his colleagues in Moscow while they were sitting at their desks. Five died during the attack, while a sixth died in hospital.

In response to this shocking event, State Duma lawmaker Irina Yarovaya submitted amendments to the legislation which increases liability for using weapons while intoxicated, as well as raising the age for buying weapons from 18 to 21.

The Interior Ministry announced as well that the regulations for selling weapons to citizens should be toughened.

Another accident took place last April in the city of Belgorod in southern Russia, where Sergei Pomazun opened fire in a weapons store killing three people, and then shot another three people on the street outside. Five people died on the scene, including a 14-year-old girl. Another victim, a 16-year-old girl, died later in intensive care.

Last July President Vladimir Putin has signed a law that bans shooting firearms in public places.
