Grosjean went for a small gap and clipped Lewis Hamilton's McLaren. That sent both cars spinning and led to Grosjean's Lotus flying over Alonso's Ferrari, which then took out Perez's Sauber. All four drivers escaped injury.
A visibly frustrated Hamilton briefly confronted Grosjean after the incident and tapped the side of his own helmet with his finger after getting out of his car.
