A police officer drove at "eyewatering speeds" reaching up to 159mph while practising his driving skills in an unmarked police car, a court heard yesterday.
Pc Mark Milton, of Telford, Shropshire, was clocked at high speeds by an in-car camera used by West Mercia Police.
The 38-year-old was originally cleared of dangerous driving and speeding last year but the High Court overturned his acquittal and ordered a retrial. Yesterday's hearing, at Ludlow Magistrates' Court, was shown footage taken from the camera video fitted to the Vauxhall Vectra.
It recorded the vehicle, driven by Milton, as regularly travelling over 100mph on Aroads and up to 159mph on the M54 during the early hours of December 5 2003.
Pat Sullivan, prosecuting, admitted there had been some dispute over the speeds the camera had recorded, but added: "The prosecution say broadly these (speeds) are accurate and we can use them as a guide."
"Pc Milton was travelling at eyewatering speeds," he said.
The allegations also include Milton driving at 131mph on the A5 and 91mph in 30mph areas. Milton, who had worked for West Mercia Police for 12-and-a-half years and became an armed response officer in 1994, has always denied the allegations.
Inspector David McWilliam, based at Telford police station with Milton, told the court the constable had told him he was experimenting with the Vectra as he had not driven it before.
He told the hearing: "He said to me 'I have no excuses, I was trying to see what the vehicle could do'."
Later in December Milton made a statement under caution to investigating officers.
He said in the statement - read out in court - he had taken an advanced driving course and the reason for his high-speed driving was to practise the skills he had learnt. He was told by his advance driving trainer that he should "take time to maintain and hone his driving skills", the court heard.
The trial continues.
