Naomi Campbell in wheelchair after she was violently robbed in Paris

Naomi Campbell suffered a to ligament in her leg after she was violently attacked and robbed on a Paris street, it has been revealed.

The British supermodel was recently sporting a cast on her leg for a mystery injury - and it has now emerged that she was set upon by a group of thugs after she tried to hail a cab in the French capital last month.

A source told the New York Post: '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 unclear what the thieves managed to take from Ms Campbell, but it has been suggested they were trying to steal valuable jewellery she was wearing at the time.

The 42-year-old's billionaire boyfriend, Vladimir Doronin, used his private jet to fly her to Vail, Colorado, where she was treated by J. Richard Steadman, one of the world's leading orthopedic surgeons.

The model has been using a wheelchair and crutches to get around following the attack, and Vladimir has increased the size of her security detail as a precaution.

French police are currently investigating the incident, and have apparently asked the model not to speak publicly about her ordeal.

Ms Campbell declined to comment on the attack, but told the Post that she is now 'fine'.
