A man has been arrested with two handguns at a hotel at Disneyland Paris, police said.
The man, 28, was also carrying a copy of the Koran when he was detained at the entrance of the building, according to reports.
A French police official said no one had been injured in the incident.
There are several hotels around Disneyland Paris, which attracts thousands of British holidaymakers each year and is among Europe's most-visited tourist attractions.
France remains under a state of emergency since the deadly Islamist attacks in Paris in November which killed 130 people.
