Acid Attacks on the Rise
Crime in the UK
The Met points out that there is not one specific offence for 'acid attacks', so the numbers are based on offences that had the feature code 'Noxious/Corrosive Liquid' or any offence with an code called 'Causing explosions, sending explosive substance or throwing corrosive fluids with intent to do grievous bodily harm.' "Each individual record would have to be read to determine the exact nature of the corrosive fluid and how it was used in the attack (e.g. was it thrown? etc.)," the relevant document states.
