A policewoman stationed outside French President Francois Hollande's residence in central Paris was injured when a motorist deliberately drove his vehicle at her on Wednesday night, French media reported.
According to BFM TV, the driver was driving the car on the wrong way along a one-way system.
Two people have been arrested, Reuters reported.
The attack comes exactly a week after a policewoman was shot dead in southern Paris last Thursday by terrorist Amedy Coulibaly, who later went on to kill four hostages at a kosher supermarket before he was shot down by the police.
The attack had come immediately after the shooting at Charlie Hebdo office where 12 people were killed.
France has been on a high terror alert since the attacks and has deployed thousands of troops to guard 'sensitive sites', especially synagogues and mosques.
It is, however, not clear if the latest incident is connected to last week's attacks.
