Police have appealed for help identifying a nuisance biker.
Over the last few days, the Great Horton and Little Horton Neighbourhood Policing Team have had numerous reports of off road bikes and quads speeding around the Canterbury and Great Horton areas of Bradford.
Police say though they welcome the reports, they have been difficult to follow up without any detail of the vehicle or the rider.
They have asked for anyone with information, or photos and videos of the bike, to now come forward.
An NPT spokesman said: “Whilst we thank the public for calling in, it is difficult for us to take action without being able to identify either the bike or the rider.
“The more evidence we have in relation to this the more action that we can take.
" If you know who owns this bike, where it is being stored or who is riding it, then please contact your local NPT office on (01274) 376388 or via crimestoppers on 0800 555111.”
