A teenage boy was arrested after a dramatic police chase in North Yorkshire.
It began when officers spotted two quad bikes travelling together on the A65 near Settle in suspicious circumstances, at 2.20am on Monday.
A police stinger was deployed near Gargrave, stopping one of the quads.
But the rider got on the other quad and sped off.
The remaining quad was pursued towards Ilkley along the A65, before it turned down a track at Draughton and came to a stop. Both riders ran off.
A 15-year-old boy from Bradford was located in bushes nearby a few minutes later and was arrested. The other was not found, despite an extensive search.
The two Honda quad bikes, which had been stolen from a farm in Horton-in-Ribblesdale, were recovered and will be returned to their owner.
The 15-year-old was arrested on suspicion of theft of a motor vehicle, burglary and dangerous driving. He was released under investigation while enquiries continue.
Anyone with information about the second suspect should contact North Yorkshire Police on 101.
There were 47 quad bikes stolen in Craven in 2017, compared to 22 in 2016 and 12 in 2015. Police are urging residents in rural areas to take extra steps to secure quad bikes and other vehicles.
