Srinagar, Oct 26: Eight female students of a university in Jammu and Kashmir fainted on Thursday inside the campus after an alleged 'spray attack' by unknown persons, officials said. The students of the Islamic University of Science and Technology (IUST) in Awantipora in Pulwama district were shifted to a health centre from where they have taken for specialised treatment to Sher-e-Kashmir Institute of Medical Sciences (SKIMS) in Srinagar. The students said a similar attempt had been made on them a few days back but it failed. The university said a committee had been formed to investigate both incidents. The general surmise among victims of braid chopping in the Kashmir Valley is that attackers use some anaesthetic spray to overpower them.
