The accused has been identified as Nishant Saini, a resident of Sarojini Nagar in Delhi, they said.

In her statement to police, the victim alleged that Saini attacked her several times with the hammer in a hotel after she ended the relationship with him, Deputy Commissioner of Police (southwest) Devender Arya told news agency Press Trust of India.
She said she ended the relationship because Saini did not have any job and when she told him about it, he got infuriated.
The woman told police that Saini even lied about clearing an audition for a TV serial in Mumbai.
