Police have named a man who died in an alleged road rage incident in Kirkham as Andrew Dean.
Mr Dean, 46, died after being struck by a car near the junction of the A583 Kirkham Bypass and Freckleton Street at 4.15pm yesterday (Thursday July 18).
Officers believe Mr Dean had been driving a white Renault Master van westbound on the A583 when he was involved in an altercation with another motorist driving a metallic blue Nissan Micra car.
Both vehicles later stopped close to the junction and Mr Dean got out of the van to speak to the Nissan driver.
It is believed the Nissan then collided with Mr Dean who suffered fatal injuries.
An 18-year-old man and 18-year-old woman, both from Ashton-under-Lyne, a 17-year-girl from Stalybridge and a 16-year-old girl, from Audenshaw, have been arrested on suspicion of murder.
