A teenager has been arrested after a woman was killed in a motorbike hit-and-run.
The woman, in her 70s, was hit as she crossed the road at the junction of Queens Drive and Moor Lane in Liverpool at about 17:00 GMT on Saturday.
Police said the biker rode off against the flow of traffic. The woman died in hospital.
The teenage boy has been held on suspicion of causing death by dangerous driving.
The boy, who has also been detained for failing to stop at the scene of the collision, will be interviewed by police.
A Merseyside Police spokesman said he "voluntarily attended" a police station in Liverpool.
Officers continue to appeal for witnesses and for anyone who saw an orange scrambler-type motorbike being ridden in the area to contact them.
