OKLAHOMA CITY - Thousands of Oklahomans head to a popular event each year but officials say a man attending ended up in handcuffs.
Authorities say 49-year-old Richard Britt, a convicted felon, was arrested at the Gun and Knife Show this past weekend.
Investigators say Britt purchased guns online and at trade shows in order to resell them for a profit.
Police were called to the show after someone reported that Britt was not supposed to be in possession of any firearms.
When he was confronted by officers, authorities told him that he could not have a firearm after his felony conviction.
According to the report, he said, "Yeah, I was only imprisoned for nine and half months and it was so long that I thought they had pardoned it."
Officials say he was selling weapons at the show but they found an even larger arsenal at the man's home.
Capt. Dexter Nelson, with the Oklahoma City Police Department, said, "Mr. Britt was in possession of at least 15 firearms of 10 different calibers, including assault rifles and two of the weapons were deemed to be fully automatic, which are illegal for anyone to have."
At least one weapon was reported as stolen and Nelson says he also had 33,000 rounds of ammunition.
Britt was charged with possession of a firearm after a felony conviction.
