Detective Superintendent Carl Mehta, said: "Our thoughts continue to go out to Alice's family as our search continues in a bid to find her.
"I would like to thank the local community who have shown great support to the search effort and police investigation so far. Our officers are working through the weekend - carrying on those searches. We will not stop our hunt for Alice.
"Whilst we have already seized many hundreds of hours of CCTV we still need the public's help. If you are a shop owner, have CCTV at your home, or were out filming in the areas of Ealing and Hanwell and have footage from the afternoon of Thursday 28 August when Alice was last seen, and right up to the 3 September when Arnis Zalkalns was last seen, then please get in touch with us. Save the footage, call into our incident room on 020 8358 0100, or call Crimestoppers anonymously on 0800 555 111."
