The Crown Prosecution Service (CPS) has defended its decision to prosecute a Lincolnshire driver who flashed his lights at other motorists to warn them of a mobile police speed trap.
Michael Thompson was pulled over by officers in Grimsby in July after flashing at several oncoming cars to warn them about the speed gun.
Thompson, of St Augustine Avenue, Grimsby, was charged with wilfully obstructing a police officer in the course of her duties and found guilty when he appeared at Grimsby Magistrates’ Court last week.
He was fined £175 and ordered to pay £250 costs and a £15 victim surcharge after the half-day hearing.
Thompson claimed he was merely trying to warn motorists to prevent them braking dangerously when they saw the speed trap.
Others have questioned whether the prosecution was a worthwhile use of CPS and police resources.
But a CPS spokeswoman said: “Cost is not a consideration in our decision to prosecute.
“When a file is provided to the CPS from the police, it is our duty to decide whether it presents a realistic prospect of conviction and whether a prosecution is in the public interest.
“In accordance with the Code for Crown Prosecutors a prosecution was deemed appropriate.”
