She also questioned the arrests of two security guards of Kalkaji's South Park apartment.

Sarna, who completed his high school from New York, was to return to Canada for further studies but died after a drug party Sep 13 night organised at one of his friend's flat in the south Delhi apartment. He had succumbed to a fatal head injury at the AIIMS later in the night.

Police had later arrested the two security guards, Naresh Mishra and Surender Bali for culpable homicide as well as Sarna's four friends - Shivang Gambhir, Madhav Bhandaru, Rhythm Girhotra and Pranil Shah - for having procured and consumed LSD which is banned under the Narcotic Drugs and Psychotropic Substances (NDPS) Act.
