French police arrested a man suspected of stabbing three women in the Paris metro, prosecutors said.
The three victims were stabbed at three different locations along the French capital's Line 3 metro that runs across central Paris, the RATP authority that runs the transit service told AFP.
The attacks happened between 4.15pm (3.15pm GMT) and 4.45pm at the stations Republique and Arts et Metiers - both next to the Marais district - and the Opera station, the RATP said.
"The victims were quickly taken care of by the emergency services," it said.
Police used surveillance-camera footage and mobile-tracking tools to locate the suspected attacker in the Val d'Oise region north of Paris, said prosecutors.
"Activating the geolocation of his mobile phone led to his arrest late afternoon in Val d'Oise," they said.
"The police are on site. Back-up security teams have been deployed to reinforce safety on the line," it added.
Last week, French Interior Minister Laurent Nunez called for "maximum vigilance" in a message to senior officials.
Due to the "very high level of the terrorist threat" and "the risk of public disorder", Mr Nunez asked local officials to strengthen security measures across the country with a visible and deterrent presence.
