There were five drone sightings over Tuesday night, including one near the Eiffel Tower, but there is no link yet to the Al-Jazeera arrests.
Afrasianet - Three Al-Jazeera journalists have been arrested for the alleged illegal flying of a drone in Paris after being spotted by police in the Bois de Boulogne area.
A spokesman for prosecutors said there was "no relationship for the moment" between the arrests and mysterious drone flights over the city at night.
Al-Jazeera said the journalists had been "filming a report on the city's recent mystery drones".
Drones were spotted over city landmarks for a second night running on Tuesday.
Flying drones over Paris without a licence is banned by law.
The offence carries a maximum one-year prison sentence and a €75,000 (£55,000; $85,000) fine.
A judicial source told AFP news agency of the three people arrested: "The first was piloting the drone, the second was filming and the third was watching."
The names and nationalities of the journalists have not been released. Al-Jazeera is a Qatar-based satellite TV channel.
