Nidhi Kumar, hailing from Ramgarh district in Jharkhand, was taking coaching at a private institution for pre-medical entrance test for the last six months here, Sub-Inspector of Jhawarnagar police station Jitendra Singh said.
The girl was in depression and prima facie stress due to studies and low ranking in coaching institution's tests appear to be the reason behind her suicide, he said, adding, no suicide note was found from the spot.
The body has been kept at Maharao Bheem Singh hospital for postmortem, Singh said, adding, her parents have been informed and the matter is being investigated.
