The BBC has captured dramatic footage of police officers chasing a man riding a motorbike at speed on a public road.
West Yorkshire Police said it had received almost 500 complaints from residents in north-west Leeds alone so far this year.
PC Steve Clark said many of the bikes being ridden were "death traps", often stolen or uninsured.
