My comment was based on the fact that the police/authorities rarely if ever arrest/prosecute this blight on society for fear of being accused of being racist in our pathetically over protective country. Hence jokingly I hinted you might have dreamt the whole arrest scenario.
The fact that the Gwent police actually did something is a plus. My ex step father was a Det/Sgt in them, my former Father in Law was a C/Insp in the West Yorkshire force & both would be spinning in their graves at the pathetic pc, limp wristed approach to villains of any sort , never mind pikeys. How the f**k these useless, thieving excuses for human beings managed to get themselves categorised as an "ethnic minority" is farcical. As a former g/f in the old DDR once said after encountering Roma on a holiday in Rumania, "This man Hitler he had the right way of dealing with these filthy scum" !
