Businessman, 58, who mounted jamming device on his BMW to block police speed cameras is jailed for three months
- Michael Twizell was driving BMW 3-series in Harrogate when device was spotted
- Gadget just above the car number plate generates an error message in system
- 58-year-old was jailed for perverting the course of justice and fined £1,500
A businessman has been jailed after he tricked a speed camera by attaching a jamming device to the front of his BMW.
Michael Twizell managed to outsmart a police safety camera van parked on the side of the A658 in Harrogate, North Yorkshire with his laser jamming device last February.
Police launched a probe when the camera system flashed up with an error message – suggesting someone had tampered with it.
The 58-year-old who lives in a large £400,000 house in Dewsbury, West Yorkshire, was sentenced to three months in prison at York Crown Court today and ordered to pay a £1,500 fine for perverting the course of justice.
The jamming device works by blocking the signal used to monitor how fast cars are travelling.

What is a speed camera jammer and how does it work?
Laser jammers are devices that can block speed camera signals used to detect how fast cars are going.
Speed cameras function by flashing an invisible light at oncoming cars to measure their speed.
Jammers operate by sending out a laser signal of a similar frequency, which effectively cancels out the camera’s one.
This creates an error message and fails to capture the speed of the car.
They can usually only outsmart moving cameras as static ones use the traditional formula of speed over distance by taking multiple pictures of the vehicle.
While laser jammers are legal to buy and sell to use as parking sensors or garage door openers, it is not legal to trick a speed camera.
Their use comes under laws against perverting the course of justice, which can carry custodial sentences and/or fines.
Investigators discovered the device fixed to the front of his BMW 3 Series and arrested him.
Sentencing, the judge told Twizell: ‘The police have a duty to protect us from speeding vehicles’, adding that the device Twizell used interfered with that process.
He said perverting the course of justice was a ‘serious’ offence and the courts ‘must stop people offending in this way’, adding that he had no choice but to impose an immediate custodial sentence.
Speaking after the hearing, Traffic Constable Andy Forth, from the Traffic Bureau Investigations team at North Yorkshire Police, said: ‘To use this device which was capable of interfering with police speed measurement is clearly, as shown today, a very serious matter.
‘Drivers may face a custodial sentence for using such a device in this way.
‘North Yorkshire Police will continue to investigate similar allegations when people use these devices to interfere with the normal course of justice.
‘I advise anyone who may have a similar device fitted to their vehicle to think about the consequences of using such a device and strongly recommend that they remove it from their vehicle to avoid a future prosecution.’
