Following comments we have received, I feel it is necessary to explain the process which led to the publication of today's story about some public Wi-Fi systems in Chester enabling anyone to access porn websites.

This issue of public Wi-Fi enabling people to access pornographic sites in towns and cities across the UK was originally highlighted in the national media at the weekend.

We decided to follow this up from a Chester perspective and discovered the claims made nationally were very much relevant to our local area.

Obviously it is a matter of opinion as to how important or otherwise readers may feel the story to be but we can assure you that when we raised the matter with the Cathedral, they took it extremely seriously, hence the reason why they immediately took action on their Wi-Fi system.

Indeed, officials at the Cathedral thanked reporter Rachel Flint and The Chronicle for bringing it to their attention.

The issue of access to online pornographic material has been deemed so important that Prime Minister David Cameron took action which led Google and Microsoft to set out a number of measures to block images and videos of child abuse from their search engines - a move which drew praise this week from Chester MP Stephen Mosley.

No one is suggesting such material was featured on the sites it was possible to access via public Wi-Fi in Chester but it does lead to concerns than anyone with a mobile device - including children for whom a mobile phone or tablet device is a common possession these days - may be able to gain access to material that is unsuitable in inappropriate places such as religious buildings and even children's book departments.

Our article aimed to raise awareness of such possibilities so that businesses and organisations who provide free Wi-Fi - but who are likely to be completely unaware of this potential consequence - can take appropriate action. We are pleased to report that in almost all cases where we drew it to such an organisation's attention, they decided to take such action to prevent future access to pornographic sites.
