Cyber bullying a common problem

There's been plenty of high profile cases recently where cyberbullying has been identified as the cause of injury and even death. Bullying on the internet and mobile phones is an increasingly common problem among today's youth, according to new research.

A recent study by the US National Crime Prevention Council and research firm Harris Interactive found that more than 43 per cent of US citizens aged 13-17 have experienced cyber-bullying in the past year.

Just last week, a US woman was indicted on federal charges of fraudulently using a MySpace account to pose as a teenaged boy. Prosecutors allege that her actions ultimately caused a 13 year-old girl to commit suicide.
