Officers in Dereham had been searching for the vehicle after a report of concerning behaviour behind the wheel. The vehicle was stopped late on August 5 by officers, who quickly discovered it was untaxed. "This warning means if he or the vehicle is seen causing anti-social behaviour within 12 months it will be seized." Anyone concerned about anti-social or dangerous driving is encouraged to report incidents online. The force's website offers a 'report a road traffic incident' tool, which also allows users to submit video evidence.
