The mother of a 15-year-old girl who has been missing for almost a month has appealed for help.

Leah Burns vanished after leaving the Manchester Dental Hospital in early February and has not been seen since.

Her mother, Clara Burns, is urging anyone who may have seen her to come forward.

'I just need her home' Ms Burns told the Manchester Evening News.

'She has come off all her social media, which is not like her. Her phone was never used after she went missing' she added.

'When she meets new people she is very shy and really polite.

'When you get to know her she is a very hyperactive and funny girl and she likes to joke about.'

Leah grew up in Stockport and Stretford but has links to Manchester. She has not been seen since she left the Manchester Dental Hospital at 1pm on Wednesday February 7.

Leah, who has two younger brothers, is described as 5ft 6in, white British, with green eyes and long brown hair which goes down to her hips.

She was wearing a blue bomber jacket with a fur trim on the hood and blue jeans, as well as a distinctive necklace with a blue Winnie the Pooh child's dummy attached to it when she went missing.

Her mother said the necklace is of 'huge sentimental value' to Leah and she always wears it.

Anyone who sees Leah is asked to call 101 quoting missing ref: MP/14/0083595
