Terrorism has been ruled out over the arrest of a man who tried to bring two handguns into a hotel at Disneyland Paris, a French prosecutor said.
Searches of the man's phone records and various locations turned up no link with terrorism, Meaux prosecutor Dominique Laurens said.
The man was moving house and feared his weapons would be misplaced or taken, she said.
The man was detained on Thursday along with his female partner, who was cleared of complicity, the statement said. He remained jailed on Friday.
No one was hurt and the park - Europe's most-visited tourist attraction - remained open after the arrests at the New York Hotel.
France is under a state of emergency since Islamic extremist attacks around Paris in November that killed 130 people.
