A motorist has been arrested following the death of a cyclist in a road crash on the A55 on Anglesey.
The rider, aged in his late 20s and not from north Wales, was with a group of five cyclists who were thought to be on a sponsored bike ride.
The incident, involving a silver Vauxhall Corsa car, happened between Gwalchmai and Llangefni at 1017 BST on Wednesday.
North Wales Police said the driver had been bailed pending further inquiries.
Three fire crews joined ambulance crews at the scene, near the junction with the A4080.
"The cyclist was amongst a group of five cyclists and police are anxious to speak to anyone who saw the group or who witnessed the incident," said a force spokesman.
