A 90-year-old woman was viciously attacked and sent flying to the ground after her granddaughter was sucker punched and fly kicked by a thug
Worried for her grandmother, 29-year-old Jacqui runs up and asks Sargent if he'd taken any of her money, Nine News reported.
Within seconds the 36-year-old snaps and punches the young woman in the face before he begins to walk away.
As the 90-year-old begins to console her granddaughter, Sargent runs at the pair and delivers a fly kick to Jacqui's head.
Jacqui is sent flying towards her grandmother and they clash heads, before the 90-year-old falls backwards and brutally hits her had on the pavement.
'I couldn't believe it was happening and then I was knocked out, my head on the pavement and I couldn't remember much,' Carmen said.
The court was told Sargent, who is a paranoid schizophrenic, was under the belief the two women were witches and used sorcery on him.
Sargent was sentenced to 11 months in prison for the violent assault that left Carmen with two black eyes and a wound on her face that required several stitches.

Doctors confirmed the 90-year-old is lucky to be alive as the fall could have killed her.
The brutal assault was just one incident the 36-year-old was caught up in over a three day violent rampage that occurred because he didn't take his medication.
Sargent also chased a neighbour while holding a metal pole and punched a hospital worker.
Although the magistrate was sympathetic due to his mental illness, it's believed monitoring Sargent while in the community wasn't effective.
