A couple have come forward to tell police that they saw the rucksack belonging to missing Hanwell schoolgirl Alice Gross.
The purple bag was found on the towpath beside the River Brent between Hanwell Bridge and the Grand Union Canal on 2 September, five days after the 14-year-old disappeared.
Detective Chief Insp Andy Chambers said: "A couple have come forward to tell us that they saw Alice's bag on the evening of Thursday, 28 August, at about 20:15, on the footpath that runs besides the River Brent between Hanwell Bridge and the Grand Union Canal. They didn't move the bag or look inside it. So I'm continuing to ask for anyone else who may have seen Alice's rucksack between this time and when officers found it on September 2."
Alice's iPhone was missing from the rucksack and lost signal later on the day she vanished. Police are keen to trace it. The phone is a white iPhone 4S, with distinctive cracked rear case that Alice had decorated with marker pen.
Alice, who attended Brentside High School in Hanwell, is 5ft 2in (1.57m) tall and of very slim build with shoulder-length, light brown hair. She was wearing dark blue jeans and a grey top, and tartan framed glasses when she was last seen.
Detectives say they've had a "great response" from the public, but still no confirmed sightings after she was last seen on CCTV. They will appeal for information on Crimewatch on BBC1 tonight at 10.40pm.
