Ealing runners support Alice Gross campaign
Thousands of runners in the Ealing Half Marathon in London have been showing their support for the campaign to find missing schoolgirl Alice Gross by wearing yellow ribbons - the symbol of the #FindAlice appeal.
The race route takes in an area which includes the home and the school of the 14-year-old, who went missing on 28 August.
Meanwhile the RAF has been drafted in to help find her, as police continue to examine footage from hundreds of CCTV cameras for clues.
