Third of Teens Online Report 'Cyberbullying'

Nearly a third of teenagers who regularly go online say they have been harassed on the Internet, with girls and participants of social-networking sites more likely to be targets, a study finds.

However, two-thirds of teens say bullying and harassment occur more often offline.
