Nico Rosberg beats Lewis Hamilton in second practice in Bahrain

Mercedes' Nico Rosberg sets the top time in an eventful second practice session at the Bahrain Grand Prix.

Rosberg was over a tenth of a second clear of team-mate Lewis Hamilton with Ferrari's Kimi Raikkonen and Sebastian Vettel third and fourth respectively.

Vettel is at the centre of an investigation after tangling with Force India's Sergio Perez on his way into Turn One and Raikkonen and Hamilton could be in trouble after jumping the queue in the pit lane after the restart.
