French police arrested a man carrying two handguns at the Disneyland Paris amusement park outside Paris on Thursday, an Interior Ministry official said.
A police source said the 28-year-old man of European origin had been carrying the two guns, including an automatic handgun, concealed in a bag that also contained a copy of the Koran religious text.
A woman who had been accompanying the man was also arrested, the source said.
France remains in a state of emergency since Islamist gunmen and suicide bombers killed 130 people in a series of jihadist attacks in and near Paris in November.
A spokeswoman for Euro Disney, which runs the amusement park and whose main shareholder is U.S.-based Walt Disney Co., had no immediate information to offer about the incident.
The man was unknown to police prior to the incident and his bag set off a security alarm as he went through a metal detector at the park's New York Hotel, the police source said.
