The MPS tracks offences monthly for trends in the type of offences where a corrosive substance has been used, and importantly where they are occurring. This allows BCU’s to deliver a local response and may include a focus on particular offenders for enforcement activity as well as other tactics. All MPS officers have been trained in the response to an attack and on the joint CPS protocols to follow to ensure positive criminal justice outcomes are delivered. The MPS remains a key member of the national working group and are involved in the ongoing development of solutions for street-based testing that will support the new offences of the Offensive Weapons act, when introduced. The MPS continues to see a reduction in offences since the peak in the year 2017, with offences in 2019 being 43 per cent less than that period.
