Upset after being scolded by his younger brother, a 45-year-old mentally unstable man in Rajasthan's Kota killed him with an axe, police said on Sunday.
Family members said the man would urinate in his room or verandah of the house, due to which they would be left embarrassed. It was for the same reason that his brother scolded him.
Infuriated, the man picked up an axe and attacked his younger brother, inflicting severe blows on his head and other parts of the body and fled the scene. He was rushed to a hospital but could not be saved.
