Video-blogger searches for stranger who saved his life

A video-blogger has launched a campaign to find the man who saved his life.

Jonny Benjamin, 26, was on a ledge of Waterloo Bridge in January 2008 after being diagnosed with schizoaffective disorder, when a man intervened and stopped him from jumping into a river.

Mr Benjamin returned to the bridge to launch his appeal and hand out flyers to people.

BBC London's Ayesha Buksh spoke to Mr Benjamin and Jane Hughes, from the mental health charity Rethink Mental Illness.
