Mumbai: Mumbai Police Commissioner Ahmed Javed today said parents have a pivotal role to play to guard against the youngsters joining terror outfit ISIS.

"An alert parent goes a long way and the major worry is how Islamic State of Iraq and Syria (ISIS) is using the cyber-world to get into the mind of youngsters, who have grown up in the liberal democratic lives like France etc," Javed said during an interaction with industrialists and cyber expert Vijay Mukhi here.
