The CBI on Tuesday filed a status report of Najeeb Ahmed disappearance case in a sealed cover in Delhi High court and sought more time to complete the investigation.
The high court fixed the next date of hearing on 21 December.
Najeeb, a first-year MSc Biotechnology student, has been missing from the Mahi Mandavi hostel in JNU since October 16, 2016.
27-year-old Najeeb went missing after a scuffle at his JNU hostel allegedly with ABVP activists.
The RSS students wing has denied any involvement in his disappearance.
Najeeb's family members are still running from pillar to post to trace him. His mother Fatima Nafees had moved to the Delhi High Court in November last year, seeking directions to the police to trace her son.
The case was handed over to the CBI after the High Court was dissatisfied with no progress made by the Delhi Police. The CBI investigation is still underway.
