The incident that took place on Sunday night on the banks of a canal in the 19th arrondissement, in the northeast of the capital, was not initially being treated as terrorism, officials were cited as saying by the BBC.
The assailant attacked strangers, initially stabbing two men and a woman near the MK2 cinema on the Quai de Loire, along the Ourcq canal, shortly before 11 p.m, according to the newspaper Le Parisien and the news channel BFM TV.
A group of men playing pétanque nearby tried to stop him -- one of them threw his pétanque ball at him -- but the attacker continued down a side street and attacked more people, including the British tourists, the reports said.
"Solidarity with the victims and profound gratitude for the firefighters and the emergency services who immediately arrived, and for the police forces who enabled the arrest," Mounir Mahjoubi, the junior minister for digital affairs in the French government, tweeted.
