Little blue light.

An interesting drive back up the M6 today.  Mr. C. happily driving home says “ wow there’s a police car coming up fast on the hard shoulder”. It shot out infront of us followed by an assortment of marked and unmarked cars.  Seemed to do a lovely pincer move a couple of hundred yards ahead. A plume of black smoke and it was all over.
Being the excellent photographer that I am I managed to miss the main scene and just got the side of one of the unmarked cars.
No idea what it was all about but very appreciative of their superb driving abilities.
