A MAN in his 30s has been arrested after filming himself driving at 'dangerous' and 'unacceptable' speeds down the motorway.

The suspect posted a video of himself driving a Nissan at around 160mph on the M4 - between junctions 16 and 18 - on social media at 12.45pm on Sunday, January 28 which was shown to Wiltshire Police.

The driver was arrested on Tuesday night, January 30 on suspicion of dangerous driving and his vehicle has been seized for examination.

Sgt Ben Cox said: “This is completely unacceptable.

“Driving at speeds like this can so easily end in disaster as you have no time to respond to anything.

“We will not tolerate dangerous driving like this on our roads and we will ensure that those who do are found and brought before the courts.

“If you witnessed this behaviour on the M4 then please get in touch with us on 101 or via our website quoting reference 54240011186.”
