Police have released new pictures of nine-year-old Shannon Matthews, a week after she went missing in West Yorkshire.
Shannon was last seen leaving her school last Tuesday to walk 400m to her Dewsbury home after a swimming lesson.
It's very rare for a child to go missing for this long, and lots of police are searching for her.
On Tuesday night, Shannon's friends and neighbours held a special vigil later to mark one week since she disappeared.
Holding colourful balloons, they walked from the local community centre in Dewsbury Moor to Shannon's home.
A banner has also been strung across her house to try to encourage her to come home.
Shannon and her friends got a bus back from their swimming trip
The new pictures released by police show Shannon on her birthday last September, and the coach that returned her and her classmates from their swimming lesson.
It's important to remember that incidents like this are very rare.
Some of Shannon's friends think she may have run away because she wanted to see her dad, who had split up from her mum a few years ago.
Her dad thinks she may have been trying to get to his home in nearby Huddersfield.
Running away doesn't change your problems and can be dangerous and frightening
