The supermodel was targeted by two people on a motorbike who tried to grab her handbag as she sat in her car.
She was reportedly left with a torn ligament in her leg following the attack, which took place just off the Rue de Rivoli, in the heart of the French capital.
The catwalk model was later pictured sitting in a wheelchair with her left leg in a brace and it has been reported that she may need surgery to help her injuries heal fully.
French police have confirmed that two men on a motorcycle tried to grab her handbag as she sat in a car in the trendy Marais neighbourhood on November 21.
A spokesman for Ms Campbell has declined to comment on the incident and Paris police could not give details of any injuries, saying Campbell had declined an offer to be examined by doctors at the police station.
A police source said: "On November 21, two people on a motorbike attempted to steal Ms Campbell's handbag as she sat in a vehicle on Rue de Moussy. She filed a complaint with police in the 4th arrondissement but she did not agree to a medical examination."
According to reports, her billionaire Russian boyfriend Vladimir Doronin had her flown by private jet to Colorado, where she was cared for by a leading orthopaedic surgeon.
Mr Doronin is also believed to have stepped up security around the model since the mugging attempt.
There have been no arrests in connection with the case.
It is not the first time Ms Campbell (42) has encountered trouble on the road.
In 2010 she was accused of assaulting a driver from the back seat of a luxury 4x4.
The man went to the police but later apologised to Ms Campbell saying the incident was "blown out of proportion". He did not press charges.
Ms Campbell has been convicted herself of assaults on her staff and on police officers and was ordered by one judge to attend anger management classes.
