Two men are on the run after gunfire broke out at a restaurant in the Bastille district of Paris leaving at least one man wounded, according to French media reports.
France Info reported a man had been arrested, though there were unconfirmed reports of other men being sought by police after they fled the scene.
The shooting is understood to have taken place in front of the restaurant “Chez Papa” on a major boulevard in the east of the French capital at around 6pm on Thursday.
A man is understood to have been shot in the chest during the incident and is being treated by emergency service, Russia Today reports, citing a police source.
A local police spokeswoman has reportedly said they do not yet know the names of anyone involved.
Early reports suggest the incident is not terror related but an "argument that escalated", according to some French media. The cause of the gunfire is unclear at this stage.
Up to seven police vehicles are understood to be at the scene and the area has cordoned off. A video of the incident posted on Twitter shows several police cars at the scene.
The incident come four months after France was placed under a state of emergency after a string of terror attacks killed 130 people in the capital city on 13 November.
