A Sunday Telegraph investigation has revealed an alarming presence of cocaine in toilet cubicles during England's opening European Championship qualifier at Wembley.
Traces of cocaine were found in half the toilet cubicles tested in the stadium during Friday night's game (Saturday morning NZT) despite "enhanced" security checks.
Telegraph reporters tested around 20 cubicles in two areas of the stadium, with traces of the class-A drug already found on top of wall-mounted toilet paper dispensers shortly after the gates had opened.
Further cocaine was then detected after England's 5-0 Group A win over the Czech Republic.
The Football Association has since confirmed that five fans were denied entry to the match, including three who showed positive drug indications but said there were no drug-related arrests.
