Additional Chief Metropolitan Magistrate Sunil Chaudhary directed the Delhi police's Crime Branch to further investigate the matter after taking the plea of the woman complainant into account.
Seema Malhotra, the widow, in her application filed through advocate Kiran Singh, sought a direction to the police to conduct the investigation of the case properly as it involved the life of her three children.
She also referred to the fact that her elder son Aman is untraceable since December 17 last.
The woman also claimed that she apprehended danger to the life of her children due to a threat received from an associate of the arrested cab driver Lalit Ratawal.
Investigating Officer Inspector Arti Sharma, in a reply, said the matter is still under investigation.

"Let the investigation be continued and the same be completed expeditiously," the court said, directing the police to file a report on February 11.
