CCTV images have emerged showing a missing schoolgirl getting on a train, hours after she vanished from her home in Sandy, Bedfordshire, six days ago.

With fears growing for 13-year-old Atlanta Butler, police have released new images of the teenager catching a London-bound train on Thursday morning.

In the images, Atlanta can be seen boarding the 10.56am train from Sandy railway station to London St Pancras – hours after she was last seen at home by her family at 7.45am.

Officers believe she may be in London but she also has links to Milton Keynes.

Atlanta is described as having medium-length straight dark hair and blue eyes and is about about 5ft 1ins in height.
