"After any assault or attack, it's easy to focus on the physical scars - and from acid attacks, these can be particularly horrific and life-changing.

"Mental trauma often remains with the victim long after the incident."

"But attention also needs to be paid to the mental trauma that often remains with the victim long after the incident. By raising awareness about this issue, we can help to ensure that victims get the long-term help and support they need, whether it's through counselling or access to other vital health services.

"As Mayor, I'm clear that acid attacks are abhorrent and have absolutely no place in our capital. London is one of the safest global cities in the world, but in recent years we have seen an increase in these vile attacks, often linked to moped crime."

What the government are doing:

"In July, I called on the government to introduce a zero-tolerance approach, including a clampdown on the sale of corrosive substances, tougher sentences and more support for victims. It was encouraging to hear the Home Secretary's announcement last month that the sale of dangerous acids to under-18s will be banned - but the government can and must go further."

What the police are doing:

"Every Londoner deserves to feel safe in our city, whether they're out in a bar or travelling around on a scooter. The Metropolitan Police share my concerns, and take these attacks very seriously. They are cracking down on perpetrators through targeted operations, building intelligence on offenders, and increasing prevention work. We are also calling on the motorcycle manufacturers to help design vehicles that are far harder to steal.

"We have met with motorcyclists and delivery drivers to hear their concerns and experiences alongside the Metropolitan Police, and we'll be sharing these views with partners as – together – we seek to rid London's streets of these appalling crimes."
