Naomi Campbell has been injured in a street robbery in Paris, as she attempted to hail a taxi.

The supermodel suffered a torn ligament in the incident, according to the New York Post.

A source told the newspaper:

It was terrifying. Naomi believes the assailant had been watching her, casing her out, and waited for a moment to strike when she was alone. She was attacked in the street as she hailed a cab, and robbed. Her leg was injured as she was violently pushed to the ground. She was understandably very upset and shaken up.

It is not known what, if anything, was taken from the model during the incident, which happened a month ago.

Campbell has been seen using a wheelchair and crutches to get around recently, but only now has the cause of her injury been revealed.

When a reporter at the New York Post reached the supermodel, she said: “I am sorry, I do not talk to press, but I am fine.”
