The teenager who killed a Countdown security guard in a one-punch assault was on bail at the time of the deadly attack.
Sydney Jayden Kokiri, 18, appeared in the High Court today before Justice Pherose Jagose and pleaded guilty to the manslaughter of Serbian national Goran Milosavljevic.
Milosavljevic was felled by a single punch in the Papakura Countdown store on May 2, 2018, and died early the next morning.
The security guard had approached the teen, suspicious of his behaviour, according to reports at the time.
The incident was then captured on CCTV and happened in front of a number of shoppers.
