Details have emerged from the biography of a schoolboy who wanted to maim students at a school in Chelyabinsk.
Roman was diagnosed with schizophrenia as a child.
RIA Novosti reports this, citing a source in law enforcement agencies.
A teenager born in 2011 is registered at the regional neuropsychiatric dispensary.
He was diagnosed with "organic schizophrenia-like personality disorder" in 2016.
In addition, the schoolboy was registered with a neurologist from birth to ten years. The reason is a congenital pathology associated with a disorder of brain activity.
The school that Roman attacked is operating normally. He himself was taken to a mental hospital. The guy was already undergoing treatment in April-June.
It is specified that the attacker was not registered with the juvenile affairs department.
On September 16, the boy brought a knife, a hammer and a fake gun to school and then caused chaos in the chemistry classroom. As a result of his actions, three 13-year-olds were injured.
