A man made threats against the royal family after leading police on a high-speed chase, Perth Sheriff Court has heard.
Gary Bell, 41, drove through several villages at more than twice the speed limit before brandishing a golf club as police detained him.
Bell, from Auchtermuchty, had sentence deferred for reports and was banned from driving on an interim basis.
A sheriff rejected Bell’s claim that he was insane at the time of the incident.
The court heard that after being overpowered by officers following the 15-mile pursuit, Bell complained of chest pains and was taken to hospital.
PC Kevin Miller told the court: “He was making a host of irrational statements.
“There were threats against members of the royal family.”
The officer and his colleague had initially set up a speed trap, when they spotted Bell racing past.
When Bell stopped his car outside his house, the officer leaned into the vehicle to remove the keys from the ignition.
PC Miller said: “He leaned into the passenger footwell and reached for a short golf club. It has a shortened shaft.
“I leaned inside the car and started to struggle with him to prevent him using the club as a weapon.”
Bell was found guilty of driving dangerously on various roads on August 11 last year and failing to stop for police officers.
Sheriff Richard MacFarlane also found him guilty of resisting arrest, brandishing a golf club at officers and possessing an offensive weapon.
