Saw an unmarked police bike on the A2 London bound who’d pulled over a car near Bexleyheath. Couldn’t make out what bike it was as it was dark but it was a sportsbike, dark blue or black, with (surprise surprise) a flashing blue light. Rider was wearing a white helmet and hi-vis (didn’t notice any ‘Police’ markings on it though).
Something to keep your eye out for in future just in case it’s not a one-off.:unsure:
