I spoke to Nick Brett from the law firm Brett Wilson.

Generally speaking, there is no duty on any citizen to intervene in a crime that's taking place.

And often it's probably going to be unwise to do so.

There are some exceptions to that which are determined by statute.

And what are some examples of those? Well, I suppose a good one that people may be aware of is when the police will write to the registered owner of a car saying, requiring them to provide the details of the driver of a car because an offence is suspected to have been committed.

Other examples would be that there is a duty on those in the financial sector to report suspicious activity.

That is enforced by the criminal law and so a failure to report suspicious activity leading to potential money laundering offence could mean criminal prosecution for those officers.

And then what about if you're witnessing a crime or a potential crime? What obligations does a person have to report it?

in in england

well they have been i think four people have been arrested and have been released on conditional police bail so that means they haven't yet been charged and i i understand um that a coroner's inquest was opened and the post-mortem examinations are inconclusive at the moment but certainly as you as you say carbon monoxide poisoning is suspected I don't know at the present time the identity of the individuals that have been arrested, but there are four men.

One, because this took place at a holiday site, one can only... speculate that the people that have been arrested are in some way either the owners or other employees or responsible for management at the site.

And as you say, the tragic death of these two young people appears to Certainly, it appears to be suspected that it's linked to a faulty boiler, which may have caused some form of carbon monoxide poisoning.

So, yes, it's a tragic situation.

And these men, I mean, presently there is a police investigation ongoing.

We have here in Britain a public authority called the Health and Safety Executive, who are responsible for making and enforcing the laws around public safety.

So once they have that in hand, they'll go back to – reopen the inquest, present that evidence, and then will criminal charges be formally filed?
