When Alex Rins finished second in the Spanish round of the MotoGP championship at Jerez, he decided to pull off on the cooldown lap and celebrate with the crowd as a friendly marshal held his bike upright for him.

However, the marshal obviously liked the look of the sweatband that teams frequently use to cover the brake fluid reservoir, quickly removed it, and stuffed it in his pocket.

The perfect crime. Or rather, it might have been, had the whole thing not been caught on camera.
