This Dublin teen describes the moment he saved a stranger’s life

A Dublin teen’s heroic act has gone viral on social media after his story was shared on the Humans of Dublin Facebook page.

Jamie Harrington from Ballymun told the page's curator, 27-year-old photographer Peter Varga, that he had seen a young man sitting on a bridge when he was walking through the city.

"I saw this guy in his 30s sitting on the ledge of the bridge. I just thought, 'wow'," Jamie says.
