A teenager who has been missing since last week may have travelled to Kew on the day she was last seen by her family.
Alice Gross was last seen when she left her home in Hanwell at 1pm on Thursday, August 28 and it is believed she was seen near Kew Bridge later that day.
The 14-year-old told her family she would be home later that evening, but did not return.
Police are particularly concerned about Alice as she has not been in good health recently.
Alice is white, 5ft 2, of slim build and has light brown shoulder length hair.
She was last seen wearing dark blue jeans, a dark green lacy cardigan, denim blue Vans shoes and may have tartan-framed glasses with her.
Anyone who has seen Alice or has information that may assist the investigation should call Ealing Missing Persons Unit on 020 8246 1018 or charity Missing People on 116000.
