In March 2009, South Wales Police has turned to the latest Bluetooth technology in its fight to reduce knife crime. A minute-long animation, to a rap track by a young local musician, is to be sent by Bluetooth to phones by officers on patrol on the streets of Cardiff.

The rationale for using Bluetooth to broadcast the video is that,  “If you look at what most young people carry around, it is a mobile phone. It’s the one piece of technology that every young person has now. Bluetooth allows us to deliver messages like this – good quality content – that is portable, one person may pick it up and pass it on.”
