A man carrying two handguns, ammunition, and a Koran was arrested on January 28 at the Disneyland Paris amusement park.
Police say the man was "detected upon his arrival at the Disneyland hotel where he had a reservation.
Hotel security found the weapons and Koran after the man passed through a metal detector and set it off.
Papers found on the suspect indicated that he lived in Paris, but no further details were available about him.
Police say a preliminary investigation did not point to terrorism, and the man claimed he was carrying the guns because he feared for his safety.
Disneyland Paris, about 30 kilometers east of the French capital, is the most visited theme park in Europe -- with some 10 million visitors in 2014.
France remains on high alert after Islamic State gunmen and suicide bombers on November 13 killed 130 people in Paris at cafes, a concert venue, and the Stade de France national stadium.
