Metropolitan Magistrate Rashmi Gupta, after taking cognisance on the charge sheet, put up the matter for October 19 for committing the case to a sessions court as the punishment for the alleged offence is more than seven years.
The court had earlier supplied the copy of charge sheet to 34-year-old accused Surender Singh, who is currently in judicial custody, for the offence of murder under section 302 of IPC.
Police said Karuna, along with her cousin Neha, was on her way to work when Surender attacked her with a pair of scissors near Labour Chowk in Burari.
As Surender caught Karuna off guard and stabbed her with a single blade of the scissor, a man rushed to stop him but soon backed off fearing he would be attacked.
The victim was taken to a trauma centre in Civil Lines where she was declared brought dead. The accused was beaten up by the locals and handed him over to the police. He was arrested and a case of murder was lodged.
Surender, son of a retired Delhi Police sub-inspector, is going through divorce proceedings and has two kids.
