The top four runners Fabrizio Giovanardi, Gabriele Tarquini, Antonio Garcia, and Dirk Muller were all involved the same incident the Bus Stop chicane on the last lap.
Garcia tapped Tarquini while approaching the Bus Stop, which pitched the Alfa Romeo driver into Dirk Muller's BMW. Muller then slid round and back into Tarquini, who in turn again hit Garcia. The trio then lost control and spun simultaneously into the chicane.
Giovanardi, who led into the corner and had looked comfortable for the win, failed to make it though the exit cleanly, having to avoid the spinning Tarquini in front of him and scrambled home second.
BMW driver D'Aste, who started 17th, inherited the win after the bizarre accident. However, he has been demoted to second after he was deemed to have gained an advantage by cutting the Bus Stop chicane to avoid the incident.
The result means that Giovanardi was credited the win ahead of D'Aste and Tom Coronel.
