Recently in the UK, there has been a sharp rise in thugs throwing acid. There have been public protests due to widespread concern about this type of crime.
Now, prosecutors will seek "possession of an offensive weapon" charges for people who just carry the substances (usually bleach, ammonia and acid), and if someone throws it at someone, even if they miss and no harm is inflicted, they will likely bring a tougher charge that can mean a life sentence.
In the UK this year there have been already 400 acid or corrosive substance attacks officially recorded. They often are revenge or hate attacks or accompany other crimes like muggings.
