Adrian Sutil hit out at Marussia's Jules Bianchi after the pair clashed twice within the space of one lap at the Bahrain Grand Prix.
Sutil and Bianchi made contact at turn four before the Marussia driver dived down the inside of his German rival into turn one. The pair collided, with the resulting damage forcing Sutil to retire from the race.
Bianchi was handed a drive through penalty and had his license endorsed with two penalty points, bringing his total up to four.
"My race was over quite early," said Sutil. "Jules braked too late and went into my car in the hairpin. I was not able to do anything to prevent it, and my car was damaged.
"He was driving aggressively for the whole race and pushed me off at the start. With his move he destroyed mine as well as his own race. It was unneccesary. In general, the weekend was difficult for us."
Bianchi believed that Sutil turned in on him into the first corner.
"I’m really disappointed after another tough race for me; the third one in a row," he said. "I got a good start and made up three places by the end of the first lap and I was having a really good first stint, enjoying a good race with Sutil.
"I had the chance to get ahead of him and I was slightly ahead going into turn 1, but he turned in on me and crashed into me, which punctured my left rear. I pitted but after that the car never felt the same and we can see now that the floor was damaged, which resulted in a loss of downforce and made the car difficult to drive for the rest of the race."
