It's not often that rock and roll saves your life, but Ruby Wilson should thank Green Day after their artwork kept her safe from a dangerous hand grenade.
Ruby, 12, from Halifax, was clearing leaves when she found the device, and recognised it from a picture on her Green Day t-shirt.
Her dad saw her with the grenade, told her to put it down and called the army, who then blew it up.
It's thought Ruby's garden was once the site of a weapons factory.
Ten houses were cleared when she found the explosive, and experts had to take it to a school playing field to safely detonate it.
Her father Johnny Wilson, 40, said he was very worried by the incident.
If you find something you think could be explosive, you shouldn't touch it, but tell an adult straight away.
