A man has been arrested on suspicion of attempted murder after two cyclists were seriously injured in a crash with a van.
A bike, carrying a man in his 30’s and a woman in her 40’s, collided with a white Citroen Berlingo 625 En-Prise on Waterloo Road, Southampton, just before 21:50 BST on 17 July.
The woman’s injuries were not life-threatening but the man’s injuries have since become life-threatening and he remains in hospital in a critical condition, police said.
Officers want to identify the driver of another van, possibly a Fiat Scudo, who stopped at the scene immediately after the crash.
"We believe this person may have vital information that will assist with the investigation," Hampshire Constabulary said.
A 33-year-old man, from Southampton, has been arrested on suspicion of attempted murder, causing serious injury by dangerous driving, GBH, failing to stop after an accident and criminal damage.
He has since been released on bail while inquiries continue.
