Surrey Police say they received 15 calls about a smell of gas in the air this morning. Kent Police and Sussex Police also received calls about the problem. The source of the smell was later attributed to an accidental discharge from a factory in Rouen, more than 60 miles west of Paris.
Surrey Police said the smell is from an additive to the gas which has an unpleasant aroma, but is not toxic, and does not present any danger to the public.
