India, Aug. 19 -- Police had lifted the nakas in PU on Monday after an agreement with students. However, cops continued to remain present at the three naka spots to monitor traffic entering the campus.

Meanwhile, PU has hired around 50 ex-servicemen as new security guards for the campus who will join in the next couple of days to bolster campus security....
