“We understand the concerns that people living in Sutton Coldfield, and beyond, will have as a result of the tragedy that has unfolded. I’d encourage anyone with information to get in touch with the officers as soon as possible.
“West Midlands Police treats violent crime very seriously. We work very closely with partners, including public health and the Police and Crime Commissioner, to reduce its impact.
“We are working to deter young people from carrying knives through our Precious Lives project. Hundreds of thousands of school pupils have now seen the hard-hitting presentation which is designed to steer them away from knife crime. But this initiative is not enough on its own.
“We need parents, community leaders, schools and young people themselves to pass the message that it is never ok to carry or use a knife.”
