Previously unseen video of a Milton Keynes woman who vanished three years ago has been released in a bid to track her down.

Leah Croucher was just 19 when she disappeared while walking to work in February 2019.

Now a friend has released new footage of Leah laughing as she hopes it will jog someone's memory and encourage them to come forward with vital information.

The three-second video shows Leah, who has long dark hair, joking with her friend as music plays in the background.

Cops are still stumped by Leah's disappearance as no clues have been uncovered to track her down.

Her mobile phone is missing and her bank account has not been touched.

Parents John and Claire Croucher said this week that they "don't live anymore" after their daughter "vanished into thin air".

They said: "We don't live anymore. We're pretending we are [living] every long, painful day. We live in the past.

"That is where we will stay until we find out what happened on the 15th February 2019 at 8.36 am to turn off Leah's phone and cause her to vanish into thin air, never to be seen or heard of again."

Detectives have published several appeals for anyone who may have seen Leah to come forward.

Her last confirmed sighting was at 8.16am on February 15, 2019 when she was seen on CCTV walking to work in Milton Keynes.

Leah is believed to have been wearing black clothing and a rucksack on the day she vanished.

The last recorded activity on her phone was at 8.36am the same day.

A £20,000 reward has been offered by police for information that helps find Leah.
