The incident took place around 10 p.m. in Yelatma, a small village about 125 miles southeast of Moscow, BBC reported. The region, like most of the world, has been under lockdown in efforts to stop the spread of the coronavirus.
The 32-year-old man had complained to his neighbors from his balcony, prompting an argument, Russian media reported, citing investigators. He then reportedly grabbed a hunting rifle and opened fire.
All five – four men and one woman – “died of their injuries on the spot,” the investigators said.
The suspect tried to escape but officers eventually arrested him, police said. They did not release his identity.
Investigators later searched his apartment and seized the rifle – which was legally registered, police said.
The suspect's charge of murdering two or more people would carry a potential sentence of life in prison under Russian law.
