A man suspected of driving under the influence told police he is the King of Scotland and claimed diplomatic immunity, according to reports.
Nicholas Baron James, 35, was arrested last week, despite his claims.
James appeared to be intoxicated but refused a blood test, saying that his blood was "golden," the Longmont Times Call reported.
Officers spotted James swerving in and out of lanes on Main Street in the early hours of Monday, Feb. 8. He continued for almost a mile before pulling over, according to the police report.
When officers searched the car, they said they found a large knife and a prescription painkiller pill on the ground.
According to police, James demanded officers call the U.S. Department of State to check on his diplomatic immunity.
He was taken to the Boulder County Jail.
He faces charges including driving under the influence, drug-possession, traffic and violation of protective order charges.
Scotland has been under the rule of the British crown since 1707 when it was merged with England to form the Kingdom of Great Britain.
