Five people including three men and two teenage boys were arrested on Monday night after officers stopped a van on the A1041 near Camblesforth in the Selby area.
At around 6pm on 19 December, police responded to reports of an altercation between two drivers on Park Street in Selby during which a weapon, thought to be a knife, was seen.
Officers tracked the suspect vehicle, a white van, on roads through the Selby district and towards to the border with East Yorkshire.
The vehicle was brought to a stop near Camblesforth and the five occupants, all male and aged 16, 17, two aged 18 and one aged 20, were arrested on suspicion of affray and possessing an offensive weapon.
Although a knife was not found at the time, a search of the vehicle led to officers seizing a crow-bar, a wooden baton and a hammer drill bit.
