A 23-year-old man has been arrested on suspicion of dangerous driving after two people were seriously injured in a hit-and-run crash in Suffolk.
The crash happened on Saturday at 1530 GMT on Kings Road, Bury St Edmunds, when a black hatchback car hit an elderly man and woman.
The man and woman were taken to Addenbrooke's Hospital, Cambridge.
The woman has life-threatening injuries and the man has "life-changing" injuries, police said.
On Sunday evening the woman's condition was described as critical but stable and the man's condition was described as serious but stable.
Officers arrested a man from Bury St Edmunds on suspicion of dangerous driving, causing actual bodily harm, failing to stop at the scene of an accident and failing to provide a breath test.
He was arrested in Queens Road and taken into custody but later released on police bail to return to the Bury St Edmunds Police Station on 8 February.
Suffolk Police have urged anyone who may have witnessed the collision or who may have seen the small black hatchback before the collision occurred to contact them.
