Motorsport event halted and evacuated after carbon monoxide warning
A motorsport show at a Staffordshire exhibition centre was reportedly evacuated after concerns of high levels of carbon monoxide were raised.

The Motorsport with Attitude event had been putting on a full day of motorsport and other attractions as part of a weekend of action at Staffordshire County Showground in Stafford on Saturday.
However, it was reported that the event was cut short and the main building had been evacuated after high levels of carbon monoxide were reported to be in the air in the early afternoon.
A spokesman told ITV News that they received reports of high levels of carbon monoxide in the air at around 1.45pm.
One attendee wrote an angry message on the Motorsport with Attitude Facebook page, criticising the organisers for lack of ventilation and what she described as "terrible organisation".
She wrote: "3½ hours drive to stay the weekend for events. Organisation absolutely terrible, but having said that, thank goodness to the one lady who had taken control because she had been doing these events with her dad since she was a kid and managed to get things sorted and she was real nice and helpful.
"I don't understand why you ran the arena shows inside with so little ventilation, the extractors were not enough and needed for big powerful fans to push the fumes out.
