A NEW documentary focusing on the murder of teenager Paige Doherty is to air tonight.

Murder Next Door will take viewers behind the scenes of the investigation which snared killer John Leathem for the 15-year-old's brutal death.

Family and friends of the Clydebank teenager, as well as top police officers and Evening Times reporter Maxine McArthur who followed the case, are all set to feature in the documentary.

Forensic scientist searches bushes where Paige's body was found

A forensic scientist will also reveal the techniques used to unveil the roll shop owner as the killer. 

It's understood the programme will also show the gruesome interior of Delicious Deli which has remained largely untouched since Leathem's arrest in March 2016.

Paige's heartbroken mother and stepfather are also believed to have been interviewed for the show, which the duo hope will share the "truth" of what happened to their little girl.

The programme will air tonight on Channel 5 at 10pm.
