Facebook users in the UK can now add a "panic button" onto their profiles to report and prevent malicious behavior such as cyber-bullying and sexual harassment. The "panic button" -- which is a Facebook app that adds a tab onto your Facebook profile -- was created by the Child Exploitation and Online Protection Center (CEOP), a British law enforcement agency, after the rape and murder of 17-year-old Ashleigh Hall by a 33-year-old convicted sex offender, posing as a teenage boy, who she met on Facebook, according to the BBC.

The CEOP's app, called ClickCEOP, is a link not only to the CEOP Web site but also to nine other different sources of help including Childline and Beatbullying. The CEOP hopes that awareness of its app will spread amongst teenaged Facebook users when they broadcast the installation on their news feeds and pass along "badges" to friends.
