Why elite private school graduate who was allegedly stabbed by his mother in one Sydney's ritziest suburbs flew into a rampage at his dad's $5million inner city terrace

  • A court has heard why Scots graduate went on a rampage at his dad's house  
  • Ball, 23, was allegedly stabbed by his own mother in Bellevue Hill last November
  • The next month he destroyed plantation shutters of father's Paddington home 
  • Ball went to rehab and pleaded guilty to a malicious damage charge 
  • Police this week withdrew initial claims he went on more extensive rampage 
  • Those included unsubstantiated allegations he blasted hose down corridor 

An elite private school graduate who was allegedly stabbed by his own mother was suffering drug withdrawals when he went on a rampage at his father's house two days after Christmas. 

Hugo Ball, 23, pleaded guilty to malicious damage at a Sydney court this week after he turned up to his father's Paddington terrace and destroyed part of his plantation shutters late last year.

Court documents said the attack unfolded after the Scots graduate's dad, the former CEO Ian Ball, rang Hugo's doctor on Boxing Day to report that his son had been drinking.

Hugo wasn't allowed to drink when taking diazepam medication, better known as Valium. When Hugo went to the doctor the next day for a prescription, he was refused the drug.

Wrongly under the impression his father had leftover medication at his house, Hugo then turned up out the front of his dad's home on the morning of December 27, the documents said.

'The accused began aggressively banging and shouting at the front door,' an agreed fact sheet tendered in court said.  

'The accused went up to the shutters ... and has damaged several of these which caused them to snap off and has rendered them unfit for purpose.'

As part of his plea, police withdraw initial claims of a more extensive rampage that officers had made in court documents late last year.

Those unproven claims included that Ball had allegedly turned the hose on and sprayed through the letter box of his father's front door. 

It's not suggested this claim was true.

No conviction was recorded against Ball at a hearing this week. 

However, a magistrate upheld a two year apprehended violence order putting him on notice not to assault, menace or harass his father.

Hugo was allegedly stabbed by his mother, Samantha Palmer, with a 12 inch knife at her Bellevue Hill home in mid-November.

The alleged attack - the talk of one of Sydney's most affluent suburbs - resulted in Hugo losing two litres of blood, paramedics said at the time.

Palmer was charged over the alleged stabbing. Her case remains before the courts.
