An Instagram account that featured inappropriate images of young people has been shut down after school pupils raised the alarm.
The anonymously run account has been deleted, after staff at Sale High School were made aware of its existence and reported it.
The account included photos of young people in underwear. They were not children at the school.
Messages had also been sent to children asking them for inappropriate photos of themselves.
Students, who are taught in school about online safety, raised the alarm with their parents - who contacted the school.
Staff also issued an alert to all parents, urging them to check their children's accounts to make sure they were safe.
