Missing JNU student Najeeb Ahmed’s roommate, who was supposed to undergo a polygraph test on Thursday, didn’t turn up for it despite giving his consent, police said.
The polygraph test was scheduled on Thursday after Mohd Qasim, Najeeb’s roommate gave his consent last week but he didn’t turn up at Forensic Science Laboratory, Rohini, a senior police officer said.
Many of the students connected to the probe are out of Delhi because of vacations and have been asked to give their consent for the polygraph test.
