Former Manchester United star Cristiano Ronaldo faces a police quiz in his native Lisbon.

The Scottish Sun says Ronaldo, 24, allegedly flipped in his Ferrari in Lisbon when he spotted he was being filmed from another car.

The ex-Manchester United winger is said to have stopped and leapt out of the vehicle before booting a side window of the car. It shattered, sending broken glass flying over teenager Sara Pardal, 17.

Sara, who says she was filming as a fan, was treated in hospital and called cops. Ronaldo, who has moved to Real Madrid for £80million, was on his way to an Elton John gig with mum Dolores, 54, and two sisters.

His management claimed he was a "paparazzi trap" victim. And in a statement, Ronaldo apologised, claiming the girl was a snapper stalking him.

He said: "This persecution caused my mother to be so disturbed and upset that I had to stop my car to try to convince them to leave us in peace.

"When my mother is involved it is very difficult for me."
