I wonder how many more Muslim security guards for the London Olympics are illegal infiltrators? Or terrorists?

Two G4S security guards who were due to protect footballers during the Olympic Games have been arrested on suspicion of being illegal immigrants. The men, who are believed to be from Pakistan, had secured jobs with the under-fire firm to work at the City of Coventry stadium, which is due to host 12 matches.

Officers swooped on the venue after their alleged bogus status is said to have been revealed in an accreditation check by G4S, which has been criticised after failing to provide enough staff for the Games.

The firm, which last week admitted it could not meet its contracted target of 10,400 guards despite employing 650,000 people worldwide, then notified the police and UK Border Agency. The men, who are aged 21 and 24, worked for East Midlands Security and would have been part of the effort to ‘lockdown’ the venue in a bid to guard it from terror attacks.

‘The arrests by UK Borders Agency followed the proactive security checks carried out by the accreditation centre at City of Coventry Stadium in preparation for the forthcoming Olympic football matches. ‘West Midlands Police are working with officials from UK Borders Agency and the men remain in custody pending further enquiries by UKBA regarding their immigration status.

G4S has faced accusations that the crisis has been caused not only by poor management, but by hiring cheap, inexperienced foreign labour at the last minute to keep costs down. Hundreds, if not thousands, are foreign nationals, some with a very poor command of even basic English.
