Watch: Furious Sebastian Vettel drives into Lewis Hamilton during chaotic Azerbaijan GP
Ferrari's Sebastian Vettel appeared to intentionally drive his car into Lewis Hamilton's Mercedes during Sunday's Azerbaijan Grand Prix.
Hamilton had started on pole in what proved to be a chaotic race in Baku and was following a safety car at the time of the incident with Vettel.
Footage appeared to show the Briton braking behind the safety car, causing Vettel to drive into the back of him. Clearly annoyed at the incident, the German then drove alongside Hamilton's car and, after making his feelings clear with a couple of hand gestures, steered his Ferrari into it.
Several collisions in the race also saw the red flag waved during lap 22 with debris on the track.
After the race was restarted, Hamilton was forced to make a stop due to a problem with his head rest. Although Vettel was later handed a 10 second stop/go penalty for this incident with Hamilton, the German exited the pit lane ahead of his rival.
"A 10 second penalty for driving like that is not enough," Hamilton was later heard remarking over the radio to Charlie Whiting.
