One man's war on heroin in the US

A man who lost his daughter to heroin became set on rescuing other young drug addicts.

At the weekend, John Cramsey and two friends were stopped by police driving a truck full of weapons into New York City.

They told police they were intent on taking another girl out of the hands of a dealer.

At his hometown in Pennsylvania, a complex picture emerges of a man who decided to fight back against the US heroin epidemic.
