BOSTON (AP) — Two Iowa men charged with making online threats of violence at a Pokemon competition in Boston are being held without bail for at least four months.

A judge ruled Tuesday that 18-year-old Ames resident Kevin Norton and 27-year-old Boone resident James Stumbo pose a danger to society.

Prosecutors say the men made social media threats against at least one competitor at last month's World Pokemon Championships.

Police found a 12-gauge shotgun, an AR-15 rifle and hundreds of rounds of ammunition in their car. They were arrested at their hotel in Saugus, north of Boston.

Defense attorneys argued that there was no evidence the defendants planned to carry through on any threats.

But the judge in his ruling said their online postings weren't "just kids' stuff on the computer."
