THREE people have been arrested for the illegal use of police speed camera laser jammers in their cars.

Five cars with laser jammers were also seized.

When a jammer encounters a police laser it warns the driver, and sends out pulses to stop a speed reading for a period of time, allowing the driver to slow down.

Posting on Twitter on Friday, March 22, police wrote: “Using a laser jammer to avoid speed cameras is perverting the course of justice. The GoSafeCymru enquiry team in Dyfed-Powys currently has three people in police custody and five cars seized complete with laser jammers.

"Don't do it."

English police forces have previously stated: “To use a device which is capable of interfering with police speed measurement is clearly a very serious matter.

“Drivers may face a custodial sentence for using such a device in this way.”

A spokesman for Dyfed-Powys Police said: "Three people have been arrested on suspicion of fitting devices to cars to interfere with speed cameras.

"Dyfed-Powys Police arrested a 62-year-old man and two women - aged 18 and 57 - on suspicion of committing an act with intent to pervert the course of justice.

"It is suspected they fitted laser jammers, which interfere with speed cameras to five vehicles, which have been seized.

"The three people, of Ynysforgan in Swansea, have been released under investigation while further enquiries are carried out."
