A 23-year-old former domestic help, Rahul Meena, has been arrested in connection with the alleged rape and murder of a 22-year-old woman, an IIT graduate, in south Delhi's Kailash Hills area.
According to police, Rahul allegedly raped another woman in Rajasthan's Alwar just hours before committing the crime in Delhi.
He was seen entering the house in Kailash Hills at 6:28 am in the CCTV footage and was aware of a hidden smart card used for entry.
Police said after entering the house, he attacked the woman, strangled her using a mobile phone charging cable and struck her with a heavy object, rendering her unconscious.
A postmortem conducted later confirmed the victim had been sexually assaulted; strangulation was established as the cause of death.
Rahul was arrested from a hotel in Dwarka on Wednesday and has been granted four days of custodial interrogation.
