My son, 15, was slaughtered by Bristol machete gang in sick case of mistaken identity… I’m haunted by heartbreaking call

MUM-of-three Nikki Knight was on a rare night out with pals when her teenage son’s number flashed up on her phone.

Worried about leaving 15-year-old Mason Rist home alone, she had left him £20 for a takeaway and made him promise to message her if needed.

Quickly sweeping up the phone to her ear, Nikki was confused when she heard an unexpected voice as a police officer told her Mason had been “fatally injured”.
