No many details yet and certainly we see people do silly things like "forget" about bringing a gun on a plane and such. Maybe nothing but a box of ammo is kinda strange though.

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.
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.
