A bladder cancer survivor had to pull over during a 'medical emergency' that saw his catheter bag erupt - and was slapped with a £200 parking fine. John McCartney was caught short when a plastic valve fastened to his abdomen fell off and more than a litre of urine spilled out. The cancer survivor, 70, had to pull over to reattach it - so pulled up in a car park and used a nearby toilet for 15 minutes. When he returned, he discovered he had been with a £60 fine which would increase to £100 if he did not pay up within two weeks.
