The class IX student got into a quarrel with his sister yesterday evening as the family was about to visit a temple, which irked his mother and she beat him, they said.
Angered by the beating, the boy locked himself in a room and hung himself from the ceiling fan, they said.
In another incident, a 28-year-old woman committed suicide by hanging herself due to alleged harassment by her in-laws.
Police said the family members of the deceased claimed that her husband was an alcoholic who used to regularly harass her and she also faced harassment from her in-laws over dowry.
The girl's family was yet to file a complaint in the matter, they said.
