Online rapping challenge to fight knife crime
More than 100 people have joined an online campaign to tackle knife crime by recording videos of themselves rapping.
The knives down challenge was started by Cardiff-based rapper Marvin "Starz" Heron.
He said the response to the challenge has been "overwhelming" and he hopes the message will spread beyond Cardiff.
Knife crime in Wales increased by 20% in the year to March 2019.
