The knife attack on a dance class of children has left the country horrified. We do not yet know much about what happened, but a male aged 17 has been with the murder of three girls and ten counts of attempted murder.

Misinformation, distributed via social media, has been linked to after the attacks.

An attack of this kind is extremely rare. We know about the alleged attacker, except his age and name, and that the prosecution that he had an autism spectrum disorder diagnosis. At this stage it would not be helpful to generalise or try to identify conclusions but the police are not treating this as a terrorism related incident.

Attacks like these prompt calls for knife crime to be tackled and knives to be harder to access. Earlier this year, the Labour party put out an which includes the ambition to cut knife crime by half. It is early in the life of the new government and such ambitions may be realised in time.

The previous government’s included measures to limit the sale of knives and increase police powers, but it was not passed before the end of the last parliament.

The many causes of and potential solutions to knife crime are in extensive research, . Social issues including poverty and deprivation, serious mental health issues and online radicalisation are all part of the .

The lack of a proper home, violence in the home, lack of resources and money, parental neglect, adverse childhood experiences, supply of drugs and so-called are also sometimes part of the picture.

The social issues behind knife crime are well known to and law enforcement, and feature in the government’s strategy on from 2018. And yet, knife crime is in England and Wales.

What are the solutions?

One of the reasons we have not been able to tackle this in the long term is the lack of collaboration between different agencies and sectors of society. Knife crime and other violence are complex problems, but the approach in England and Wales has so far been too simple, .

In contrast, Scotland’s partnership approach has attracted international attention for its and impact. The country’s Violence Reduction Unit treats knife crime as a complex public health issue, and homicides in the decade after it was set up in 2005.

This approach involves not just the criminal justice system, but also schools, health and mental health services, probation, social services and youth outreach. (Some scholars argue that cuts to youth services have played a role in rising knife ).

Calls for a similar approach in England and Wales have been largely . We need a clear policy on tackling knife crime that spreads throughout society.

The internet – and lack of regulation – also presents concerns, specifically in the prevalence of violent material and the availability of knives.

Knife sales and purchases on are difficult to police. The National Police Chiefs Council is trying to assemble a current the availability of knives through internet retailers.

But regulating the internet has proven an intractable problem. The UK’s attempts to protect the vulnerable from online harm but is slow to with technological advances.

Recently, police have warned about a rise in people turning to extreme behaviour sparked by online activity.

Little is known about the background to this terrible tragedy, but it is clear we cannot wait for reviews or strategies any longer. We need immediate action to keep pace with rapid developments in internet regulation, and to prevent violence through a holistic approach – not just punish it after it happens.
