An Olympic security whistleblower has claimed that there is a '50-50' chance of a bomb attack at one of the London 2012 venues, according to Sky News.

The employee of security firm G4S, who was not named by Sky News, is claimed to have said budget constraints led to the cutting of corners in recruitment, and that he believes some staff are not capable of carrying out their duties.

The employee, who is involved in training staff, claimed a “no fail” policy was in existence for potential recruits, with applicants passing the training course regardless of competence.
He claimed that decommissioned weapons and grenades were passed through X-ray machines and that staff had failed to spot them - only to be told they would still get the job.
