In 2019, 90 lives were lost to knife crime in London. 1 every 4 days.

But people are often reluctant to report information, so find it hard to call the police. To overcome this, we gave them something more powerful than their reservations. The human stories behind knife crime statistics.

Five mothers of murdered sons told their heart-breaking stories through traumatic calls they made after their child was stabbed.

They showed what a hard call really is.

The production was harrowing for the mothers, who had to describe all the calls they made the day their child was murdered, then describe the most traumatic for a recording session and film shoot.

The campaign was covered by BBC, ITV, and SKY, as well as The Daily Telegraph, Daily Mail, Sun, Evening Standard, and was backed by UK Home Secretary Priti Patel.

Independent charity Crimestoppers allows people to speak up against crime, anonymously.
