Campaigner Alison Cope says four schools across the West Midlands, including one in Worcestershire, have already called her about their fears.

Alison's 18-year-old son Joshua was killed outside a nightclub in Birmingham in 2013. Since then, she's dedicated her life to teach young people about the dangers of knife crime and the impact it has on those left behind.

She tells Tammy Gooding what parents need to ask their children, and why the issue is far more than something limited to London, or only involving black communities.
