The Mooroopna boy pleaded guilty in a Children’s Court to two counts of armed robbery, lighting a fire in the open air endangering the property of others, and committing an indictable offence while on bail.
A prosecutor told the court the boy pointed a 14cm knife at another boy, also aged 14, telling him to give him his jacket and take off his pants when they were walking around the former Mooroopna Secondary College with two other boys on August 29.
The three boys then kicked him in the head and body, and the victim said “I don’t want to get stabbed”.
The Mooroopna boy then demanded the victim’s phone pin code, and said “you know what happens to snitches” and he was “going to come back with a double barrel shotgun”.
The victim was left in the middle of the parkland in the dark in his underwear after the three boys left, the court heard.
One of the boys recorded the armed robbery, which the 14-year-old Mooroopna boy sent the victim on Snapchat.
The court heard the Mooroopna boy — who was on bail for the attack on August 29 — and a 14-year-old co-accused were at a Mooroopna house with a 16-year-old on October 6.
One of the boys pulled out a 20cm long knife and told the victim to give his jumper, shoes and vape as payback for an incident the victim was on bail for.
About two hours later the boys called the victim and told him to come and get his stuff back.
However, when they met at the school oval, the Mooroopna boy pulled a knife on the 16-year-old, demanded his clothes and phone and started punching him.
The Mooroopna boy told the victim to “stop running or I’m going to stab you”, after he tried to run away.
Both 14-year-olds then kicked the victim, left him in his underwear and later lit a fire outside his home.
Police found several videos of the assault on the boy’s phone.
The court heard the Mooroopna boy also stole items from Mooroopna Woolworths with another boy on August 31.
He pulled a large knife out of his pants and yelled at security guards and another man entering the supermarket, who the boys got in an on-foot chase with outside.
They later broke into a Mooroopna massage parlour armed with knives in the early hours of September 1.
They stole a phone and $209 after threatening two employees with two large knives, and spraying powder from a fire extinguisher into a room where they had been sleeping and locking them in.
CCTV footage of the incident was played in court, and the boys had also recorded it on their phones.
The court heard the Mooroopna boy also punched and kicked a 14-year-old at his Shepparton house on August 14.
He was there with another boy, who filmed the attack after the victim had told them to leave.
The boy’s defence solicitor said he didn’t think his client “fully understands the impact of his horrendous behaviour”.
He noted the boy had no prior convictions and a significant disability.
He said because he was still young, he must be taught this type of offending could not be repeated.
He said the boy had been stabbed in the neck with a pen during a fight while in custody.
The boy will be sentenced on Wednesday, November 5.
