More than 1 in 10 young people between the ages of 15 and 18 have had sexual images of themselves shared online without their consent.
That's according to a study on cyberbullying and sexting among young people.
Almost half of young people who had a sexual image of them shared online without their consent did not tell anyone.
However, the study found that a quarter of 15 to 18-year-olds have sent a sexual image to someone by choice.
The findings were presented at the Word Anti Bullying Forum at DCU which continues today.
