French police have arrested a man carrying two guns at an entrance to a hotel at Disneyland Paris.
The man, reportedly aged 28 and not known to security services, was also discovered with a copy of the Koran and a box of ammunition, police said.
His bag triggered metal detectors as he entered the New York Hotel at the much-visited theme park.
France remains in a state of emergency declared in November after the deadly attacks by jihadist militants in Paris.
So-called Islamic State (IS) said it carried out the co-ordinated assaults that left 130 people dead.
'Routine screening'
Disneyland Paris closed briefly after the November attacks, but the theme park remained open following Thursday's incident.
"During a routine security screening checkpoint at one of our hotels, weapons were discovered in a guest's luggage through our X-ray machine," spokesman Francois Banon said.
"The police were immediately notified and the individual was arrested. We continue to work closely with the authorities and the safety and security of our guests and cast members is our utmost priority."
"There was loads of security, there were sniffer dogs, which you wouldn't see in any hotel and there was security as well," Ronan Flaherty, who was staying at the premises at the time, told the BBC.
A police source told the AFP news agency that a preliminary investigation did not point to terrorism, and that the man had said he was carrying the weapons because he feared for his safety.
