Inspector Adrian Needley, a team duty officer in Barnet, said: “There is nothing suspicious regarding this vehicle.
“The driver states that he regularly travels in this location, so please reassure the community that the police have investigated and it is of no concern.”
A spokesman for the Community Security Trust said: "CST discussed this immediately with police and very quickly with the original witness of what happened. We believe it to be a false alarm and the description of what happened is not entirely accurate.
“The driver was elderly and uncertain."
A spokesman for volunteer neighbourhood watch group Shomrim added: “We ask the community to remain calm but vigilant and report suspicious activity.”
