Yahoo! News - Hi-Tech School Bullies Working Round the Clock "The crucial difference from traditional bullying is that in the past kids who are being bullied could go home and find a safe haven," NCH associate director John Carr told Reuters.

"But if they're bullied on their mobile (phone) or on the internet, then it's ever-present," he added.

Carr said that schools were generally good in preventing bullying, but NCH wanted to make sure they were reacting to this new angle.

"This is a new and insidious development," said Carr. "It can ruin lives and lead to suicide."
