Kislay, son of Sales Tax Assistant Commissioner K K Gupta, was abducted from near his Patel Nagar house on January 19 when he was on way to board the school bus.
His abduction sparked off a series of protests, and school children held a protest demonstration in front of the Raj Bhavan in Pata on Friday. They met Governor Buta Singh seeking his intervention to secure the safe release of Kislay and two other students, who were also kidnapped recently.
