The driver of a 4x4 vehicle, who was cut up by a delivery van, shouted racist insults, braked and reversed into the front of the van causing damage, Northamptonshire Police say.
At about 9am on Thursday, April 27, a delivery driver drove a red van along Warwick Street and across the cross roads to Staverton Road by the fire and ambulance station, across the path of a dark-coloured 4x4 vehicle.
The driver of the 4x4 followed the van, pulled up next to it and shouted racist insults while driving down Staverton Road.
The delivery driver then drove into Western Avenue where the 4x4 pulled in front, braked and reversed into the front of the van causing damage, before driving off towards the Shell Garage.
"The driver of the 4x4 is described as a white man in his mid 20s," Northamptonshire Police today revealed.
Witnesses can contact police on 101 or Crimestoppers anonymously on 0800 555 111.
