A Paris policeman has been injured in an incident involving a son of Libyan leader Muammar Gaddafi and a high-speed car chase, French police sources say.
The late-night incident happened on the Champ Elysees
They say officers pursued Hannibal Gaddafi's Porsche after it had run several traffic lights on the Champs Elysees avenue early on Saturday.
A scuffle reportedly broke out between bodyguards and police after the car was stopped.
Two of the bodyguards were taken into custody, the sources add.
Mr Gaddafi, 28, was also detained, but immediately released because he has diplomatic immunity.
The policeman who sustained blows in the incident was reportedly given four days off work to recover.
The detained bodyguards, who had been travelling in cars behind Mr Gaddafi, were released later on Saturday, after a Libyan diplomatic delegation came to apologise, the sources say.
Another of the Libyan leader's sons, football player Al Saadi Gaddafi, is on a two-year contract with Italian Serie A club Perugia.
