A 32-year-old man hacked his parents and wife to death with an axe following an argument with them over a domestic issue at Samri village in the district early Thursday, police said.
He also assaulted his six-year-old son, who has been admitted to a hospital in Bhopal, police said.
"The accused, Jitendra Purwa, entered into a heated argument with his wife Sunita (30) over some domestic issue. His father Jalam (60) and mother Sharda (55) intervened and tried to pacify him," Bareli police station inspector K S Mukati said.
"However, he killed his parents and wife with an axe in a fit of rage," he said.
After committing the crime, the accused fled from the spot, the inspector said.
An offence has been registered against Purwa, he said.
