Police in the United States have arrested almost 100 workers at airports serving Washington DC as part of a continuing security crackdown started after the September 11 attacks.
The workers were detained on suspicion of lying to obtain security passes that gave them access to sensitive areas.
Those arrested included construction workers, janitors, food workers and at least two baggage screeners.
Attorney General John Ashcroft said: "These individuals are charged with gaining access to secure areas of our airports by lying on security applications, using false of fictitious social security numbers or committing various immigration frauds."
