The body, which was found in the bushes, seemed to have been lying there for the last three-four days and had started decaying after rains day before yesterday, a senior police officer said.
The clothes were also dishevelled and it seemed some animals had attacked the body, he said.
The body has been preserved in a mortuary and a medical opinion is awaited to determine the cause of death, the official said.
Police have not ruled out the possibility of her dying in the cold.
