Accident Tuesday Nigt outside MI6

Does anyone know what happened outside the MI6 HQ on Tuesday night?

I went past, saw an ambulance and a bike/scooter in the middle of the road, coned off with the police out there.

Hope they were ok.

Passed a grey R1, relatively modern one, with the police cordon around it, had been there a while as no ambulance. Although on the side of the road heading into town, the headlights were pointing towards Vauxhall, so difficult to say from that what had happened. However, the bike was still lying on its side.
