Ferrari's Fernando Alonso criticised what he considered dangerous driving by Nico Rosberg in their battle during the Bahrain Grand Prix.
The Mercedes driver was cleared by race stewards who investigated two incidents in which he appeared to push Alonso and McLaren's Lewis Hamilton off the track.
Rosberg said he preferred not to say anything until he had seen a replay.
Hamilton also refused to comment after clashing with Rosberg on lap 10.
The incident with Alonso was almost identical but happened on lap 24.
