A man has been arrested on suspicion of attempted murder after a car mounted a pavement and injured two people.
Police were called at 00:26 GMT on Sunday to reports of a black Audi A3 hitting three men on St Helen's Street, Ipswich. Two suffered serious injuries.
A man in his 40s had life-threatening injuries, while another man's condition was described as stable.
Police said they believe the attack was "targeted" following a fight at the Waterlily pub earlier that night.
Suffolk Police said a group of men were seen leaving the pub at 00:15 GMT and shortly afterwards a car was seen turning onto the street before hitting the three men.
A 31-year-old man was arrested at 01:30 GMT on suspicion of two counts of attempted murder. Police said they were not looking for anyone else in connection with the attack.
Police are appealing for any witnesses or people with dashcam footage to come forward.
