Share prices on the Frankfurt stock exchange fell more than 3.0 percent in midday trading on Tuesday, pushed down by index heavyweight Volkswagen, as it ploughed ever deeper into a pollution cheating scandal. 

Frankfurt's blue-chip DAX 30 index tumbled 3.2 percent to an intraday low of 9,627.10 points, dragged down by a 20.42-percent drop in Volkswagen's share price to 105.20 euros after the carmaker admitted that as many as 11 million diesel cars worldwide were equipped with devices that could skew emissions data.
