A documentary shown on UK TV tonight stated that 92% of those engaged in this criminality in the UK are from one country, namely Romania.
When a "foot soldier" is arrested and deported, others are right there in line ready to come to the UK and take over.
The statistics, and organisation, behind this type of crime are staggering, especially for London (but it has occurred in a lot of the large cities and towns here).
The police have video evidence of the criminals queueing up to interfere with the cash machines at banks located in the west end of London; it was also stated that this may be just a prelude to such activity forecast to take place during the time of the Olympics.
So what can you do?
One simple procedure to adopt is to use only those cash machines that are located inside bank premises or similar places, such as shops or within secured foyers, that make it harder for the criminals to interfere with the machines.
Always make a good, close inspection of the machine that you intend to use; some of the technology in use is very obvious, such as a mobile phone "double taped" above the keyboard so the PIN number that you enter is recorded by the video capability of the phone.
But, some of the tech is very sophisticated and a very good copy of the whole front face of the cash machine.
Stay away from popular ATMs such as those in the west end of London.
And, then there is the skimming your credit/debit card in places such as restaurants, but that is a whole different subject.
