Boston Police have successfully stopped two men from carrying out what could have potentially been a horrific gun attack during the Pokemon World Championships.
27-year-old James Austin Stumbo and 18-year-old Kevin Norton had both been invited to the 12th annual tournament but were stopped at the door.
Boston Police recovered two high-powered weapons from the trunk of James Stumbo's car.
A member of the private security firm that were working at the event reportedly found that they had been making threats of violence towards the tournament on Twitter.
Local Police were called and a search was carried out on their vehicles where a brand-new 12-gauge Remington shotgun and DPMS Model AR-15 rifle were found along with a hunting knife and hundreds of rounds of ammunition.
Both suspects were then arrested for Unlawful Possession of a Firearm, Unlawful Possession of Ammunition, and other firearm related charges.
Before heading to the show James Stumbo reportedly posted this picture on his Facebook page showing both guns and an 'NRA' sticker on the back of the car along with the message: "Kevin Norton and I are ready for the worlds Boston here we come!!!!"
The AR-15 rifle is one of the most popular weapons in the United States with over 5 million of them in the hands of the general public.
Hitting the media spotlight after the shooting at the Sandy Hook Elementary School in Newtown, Connecticut, the fully-automatic variant of the weapon is instantly recognisable as the M16 assault rifle which has remained the US Army's main weapon of choice since the outbreak of the Vietnam War in 1969.
