A deli owner who killed a 15-year-old schoolgirl during a "frenzied" knife attack in the back of his shop has been jailed for 27 years.

Paige Doherty disappeared on March 19 while on her way to her part-time hairdressing job in Clydebank, West Dunbartonshire.

Her body was discovered two days later by a walker in woodland, after which it was found she had suffered 146 knife wounds - including being stabbed more than 60 times.

Last month, 32-year-old John Leathem, whose shop she visited prior to her killing, pleaded guilty to murder at the High Court in Glasgow.

On Wednesday, father-of-one Leathem was told he must serve at least 27 years in prison.

Previously, a court heard Paige had inquired about a job at the deli.

Leatham claimed when she was not immediately offered it she told him: "I'll just say you touched me".

He claimed he panicked, before standing up suddenly.

Paige, who was 4'8, began screaming, with the deli owner responding by grabbing a knife from a nearby cabinet and stabbing her.

At sentencing, Judge Lady Rae described it as a "savage and frenzied" attack - adding it was "truly reprehensible and impossible to comprehend".

Lady Rae said that the court did not accept Leatham's claim about Paige's threat.

Leathem was captured on CCTV carrying Paige's body out of the shop in a bin bag and putting it in the boot of his car.

Footage also showed him leaving his shop to buy anti-bacterial wipes, bin bags and bleach.

The day after the murder, he went on a family outing to Balmaha with his wife and young child.

Two days after the killing, Leatham drove to a wooded area where he dumped Paige's body having stored it in a shed near his home.

But it was found in bushes just hours later by a walker who spotted what he thought were legs in the undergrowth.

During sentencing, the court heard psychiatrists had found no evidence of anger management issues in Leatham

His lawyer, Ian Duguid QC, described him as a "very unexceptional" individual with no criminal record.

Mr Duguid said the murder was a "spontaneous, gross overreaction".

As Leatham was led down, there were shouts of "beast" and "monster" from the public gallery.

Speaking outside court, Paige's mother Pamela said: "Today we see a monster put behind bars for the unthinkable, brutal crime he committed against our daughter Paige.

"There is no sentence high enough to justify what has happened but we can now see there is one less evil man in this world, which then makes the world that bit more safe for our kids to grow up in".

Paige's mother said her daughter's death had left "huge piece missing" in their lives that could "never be replaced".
