It is suspected that Kalu (26), a mentally challenged man, tried to barge into Gayatri Devi's residence at around 5 pm with an intention to steal, a police officer said.
Devi collapsed while she was hitting Kalu to prevent him from coming inside, he added.
Kalu was apprehended from the spot and is currently in police custody.
The cause of Devi's death is not yet clear, the police officer said.
Devi ran a tea stall in front of her residence, he said.
Her neighbours told the police that she was a heart patient and diabetic.
