Could you please tell me when this supposedly happened? I'm not asking for spesific dates, but I do know most of the FT's who used to work for Aston and still live here so I would like to ask around and see if someone know what actually happened. I don't doubt you when you say that that someone got into trouble with the PSB, but I know some of the people working there pretty well and it isn't unusuall that they check up on foreigners so it doesn't have to be that someone reported the person. It is not only the person with the L visa that gets into trouble if a person gets caught by the PSB, the school gets a pretty big fine as well, so reporting someone that worked for your school can be a pretty big chance to take.
