F1 trucks in the Catalunya paddockFormula 1 and other motor racing transporters are likely to face tougher scrutiny on return from international events at UK customs from now on, after drugs were found in the trucks of a Superbike World Championship team last month.

Officials are alleged to have discovered quantities of cocaine, amphetamines and cannabis in the vehicle belonging to Paul Bird Motorport, which runs the Kawasaki Racing Team. Four staff members from the team have been arrested and released on bail.

As a result of that incident, a source at the United Kingdom Border Agency said that there was now likely to be a ramping-up of checks on motor racing transport vehicles.

"Our intelligence analysts will be looking much more closely at motorsport vehicles from now on, including Superbikes and even Formula 1," the source was quoted as saying by Britain's Daily Telegraph. "They have been pulled over very rarely – and that will now change."
