Not that I would want to see this tested, but I imagine they would use whatever means neccessary, depending on the crime.
If, for example, you were on a bike riding through nottingham doing drive by's, they wouldn't hesitate to use whatever it took to stop you, whether you get arrested or end up in a big mac.
On the other hand, if you jumped a red light, I think they'd just follow you until you either fall off from pressure, take a detour down a narrow path, or until a Subaru Impreza (used for recreation purposes, obviously) undertakes the coppers.
