The students -- eight boys and and a girl -- were released later. The Chanakyapuri Police said the girl was asked to to leave soon after her detention while the others were let off late in the night. The girl, Mineshi Mishra, however, refused to leave without her friends.
The students had plans to meet HRD minister Prakash Javadekar and Prime Minister Narendra Modi to submit a memorandum. However, they could not get an appointment.
On a delay in release of the students, she tweeted, "Really unfortunate that despite requests @DelhiPolice is yet to release the girls. They should be immediately released."
The girl student, Mishra, alleged that during the detention period her friends were threatened by police and some of them were "deported out of Delhi".
