A man is fighting for his life after being stabbed in a mass street brawl that saw 10 people fight with weapons including an axe.
He was one of five people taken to hospital - three for stab wounds - after the battle in Bury shortly after 10pm on Friday, Greater Manchester Police said.
The force said "a number of weapons, such as an axe, a knife and a hammer were recovered at the scene" in Walmersley Road.
Three men aged 32, 24 and 22 are being questioned by police on suspicion of violent disorder over the combat, which police believe followed a car chase involving a Volkswagen Bora, a silver Seat Leon and a white Hyundai.
GMP Detective Inspector Charlotte Cadden said: "It appears the VW Bora was chased for a short period by the silver Seat Leon and a white Hyundai and a fight broke out between the occupants of the vehicles on the street.
"Extra patrols are now in place in the area, and there a number of scenes which are currently being secured by officers."
Detectives said they are searching for the Bora, registration number YE53 GHO, and a dark-coloured BMW 5 Series, registration starting MD06, which fled with two Asian men and two white men who had been in the Volkswagen.
