A Pirelli tyre test set to take place at the Interlagos circuit this week has been cancelled due to security fears after the Italian manufacturer had staff members targeted by robbers after Sunday's Brazilian Grand Prix.
Pirelli has confirmed the incident took place as personnel left Interlagos on Sunday evening, just 48 hours after a minibus carrying Mercedes team members had been robbed at gunpoint on the outskirts of the circuit. In both cases, the staff in question were unharmed.
The Pirelli incident took place despite Sao Paolo police confirming through a statement on Saturday that there would be increased policing in the evening, especially between 2200 and 2330 when teams and staff leave the track.
