Facebook adds suicide report system

Facebook is launching a system that allows users to 'report' friends who they think may be contemplating suicide.

It follows cases like that of Simone Back, who killed herself last Christmas, after telling friends online that she had taken all her pills.

The feature is being run in conjunction with the Samaritans, which said several people had used it during a test phase.

Anyone worried about a friend can fill out a form, detailing their concerns, which is passed to the site's moderators.

Rory Cellan-Jones explains.
