A 10-year-old Brownie saw a fundraising opportunity when hundreds of cars were accidentally diverted into Claygate during Ride London.

Hannah Pollock leapt into action when the village was flooded with confused drivers hoping to get to Heathrow, after cycling race organisers wrongly placed a diversion sign.

After mistakenly coming to Claygate unwitting drivers were caught up in another diversion route for the re-surfacing of Foley Road, causing further bafflement.

Hannah's mother, Lucy, said: "She made a sign saying 'Are you lost?' and gave each driver a set of instructions on how to get to Tolworth where they could then head south on the A3.

"She asked each driver for a small donation to the Princess Alice Hospice in the region of 20p to 50p.

"She was very concerned that some cars had young babies in and refused to stop until she had helped all she could."

At one point there was a queue of cars and Hannah, a member of Claygate 1st Brownies pack, had to run from car to car up the road giving directions.

A neighbour gave Hannah a glass of orange squash to fuel her efforts.

Within an hour she had made £36.18, which she donated to the hospice yesterday morning.
