Five illegal immigrants made their way into Britain last week by hiding inside trucks operated by Formula One Management.
The canvas-sided trucks, boarded by the African stowaways in Calais, were returning to FOM’s Biggin Hill headquarters in Kent from the recent Monaco grand prix.
The trucks were also carrying F1’s broadcasting equipment, and the drivers only discovered the extra cargo once the journey was complete.
FOM staff phoned police and the illegal immigrants were handed over to authorities, a UK Border Agency spokesperson confirmed.
A FOM spokesman said: “This is the first time we have had such a problem.”
