A PANIC button application has been launched so young Facebookers can report suspicious online behaviour and get internet safety advice.

All Facebook users can now access an advice centre from their homepage where they can report suspected grooming or inappropriate sexual behaviour.

The facility is the result of a joint initiative between Facebook and the Child Exploitation and Online Protection (CEOP) Centre.

From today (July 12) an automatic advert for ClickCEOP will appear on the homepage of every user aged between 13 and 18, encouraging them to add the facility to their profile.

The protection centre's new Facebook page at facebook.com/clickceop will also give users the option to add the ClickCEOP application.

CEOP chief executive Jim Gamble said: "Our dialogue with Facebook about adopting the ClickCEOP button is well documented - today however is a good day for child protection.

"By adding this application, Facebook users will have direct access to all the services that sit behind our ClickCEOP button which should provide reassurance to every parent with teenagers on the site."
