A horse has been serious injured and the rider thrown off after it was spooked by a gang of six people on quad bikes and a bicycle.
The woman was thrown from the horse but was not injured.
The horse was left with a serious leg injury.
It happened at about 3.50pm on Sunday, March 24 on Jowetts Lane in the Draughton area.
North Yorkshire Police believe that the group may have travelled from Bradford and had been sighted in Queensbury at about 1.30pm.
It is believed they then headed towards Keighley, going through Laycock and Sutton-in-Craven to Crosshills, before going towards Draughton where the incident occurred.
