Carshalton and Wallington is supposed to be one of the safest parts of London, but it has been shocked by a number of knife and violent crime incidents recently, including a knife attack in Wallington Sainsbury’s on Christmas eve, which was traumatic not only for those involved but for those who witnessed it. Can my right hon. and learned Friend assure me that victims and witnesses of terrible crimes can get access to help and support while they wait for the police to build a case?
