A seven-year-old girl died after her mother allegedly threw her from a fourth floor terrace.
Authorities believe it was the second time Aishika Sarkar had been thrown from the building by her mother, Swathi Sarkar.
Angry locals grabbed Sarkar and died her to a lamp post with electricity cable in Jaraganahalli, in Bangalore.
She was later arrested by police on suspicion of her daughter's murder.
According to police, Aishika suffered from speech development issues and was not enrolled in a school.
Her parents lived in separate houses after breaking up and her father travelled to the home once a month to give money to Mrs Sarkar.
