I only ask because I thought they only had their police powers on railway
property and a few other transport related areas (but specifically NOT roads).
However the other day I saw a BTP marked car pull over an elderly motorist on
a main road.
Are they allowed to do this or should they have called the local plod to
do it for them? If they do have police powers outside their usual areas
does this now extend to anywhere in the country (given they're a nationwide
force)?
