The killer, named in Russian media as Vladimir Levkin, is alleged to have shot two women and a man in an office on the first floor of the regional Central Bank in the city of Blagoveshchensk. All three died at the scene.
An official said: "Two women and one man are among the victims of the deputy head of the regional department of the Central Bank. One of the victims was also a deputy head of the bank, another the head of department of the bank and the third was a chief of a department of the bank."
Russian media reports suggest that the shooting could have been in response to Levkin's failure to pass certification and consequent loss of his leadership position at the bank.
An official spokesperson confirmed that personnel changes at the bank had been discussed shortly before the shooting:
"According to preliminary information, the day before [the shooting] the management of the bank held a working meeting. The discussion focused on personnel changes."
