continue to work the sources from our london bureau to find out more information about exactly what police are dealing with. what we do know that happened according to london's metropolitan police is that there was some kind of a collision involving a vehicle and pedestrians near fensbury park on seven sisters road. we just heard from kimberly dozier and our phil black earlier. this is not a typical big tourist attraction although it is a busy road in a high traffic amendment we don't know who was involved, however ples have confirmed they have made at least one arrest. i want to go back to phil black who is joining us from the london area. phil, what more are you learning? >> reporter: at this stage we are still waiting for further police confirmation about just what this could possibly be because as we've been discussing in a sense that initial description is something that will be concerning to the city given the recent events here
