Baulkham Hills, North Parramatta ‘murders’: Taekwaondo instructor arrested after mum, husband and little boy are found stabbed to death
A taekwondo instructor has been arrested by homicide detectives after a mother, her estranged husband and their young son were found stabbed to death.
Kwang Kyung Yoo was arrested early Wednesday morning, about 24 hours after arriving at Westmead Hospital in Sydney, bloodied and with knife wounds.
The arrest came after detectives questioned Yoo, the owner of Lion’s Taekwondo, about the deaths of Min Cho, Steven Cho and their seven-year-old son Benjamin.
Charges have yet to be filed against Yoo, who remains in hospital under police guard after undergoing emergency surgery for injuries to his hand and arm.
The bodies of Ms Cho and her son were found at Mr Yoo’s taekwondo studio in North Pararamatta in Sydney’s west on Tuesday, just two hours after Mr Cho was found dead in their nearby Baulkham Hills mansion.
Detectives are believed to be investigating the possibility of a love triangle and whether Mr Yoo was romantically linked to Ms Cho and whether their relationship has soured recently.

Police believe that the three deaths probably occurred within a five-hour period between 8 p.m. Tuesday evening and 1 a.m. Tuesday morning.
It is understood Mr Yoo turned up at Westmead Hospital early on Tuesday morning, bloodied and with serious injuries.
Hospital staff called in police to investigate his injuries after Mr Yoo told them he was injured at his taekwondo studio on Monday evening.
The body of Ms Cho’s estranged husband Stephen was found in the kitchen of his townhouse on Watkins Road in Baulkham Hills.
He was also allegedly stabbed.
Mr Cho’s mother is said to have arrived at the house earlier in the day to be told by police that ‘her entire family had been wiped out’.
Homicide detectives have launched an investigation after a woman and a child were found dead in Sydney’s west and the body of a man was discovered five kilometers away in Baulkham Hills.
Benjamin had just started Year 2 at Winston Hills Public School.
Shocked parents revealed they received a ‘weird text’ from the Lion’s Taekwondo studio on Tuesday morning.
The message stated that classes had been canceled because the academy’s lead instructor, Master Lion Yoo, was in the hospital.
“Due to injuries sustained from a car accident this morning, Master is currently in the hospital,” the report said. ‘That is why Taekwondo classes are temporarily suspended from today.’
One mother admitted that she knew it was “obviously not a car accident when I saw all the police outside the studio when I went to pick up the kids from school.”
Master Lion, in his late thirties, is said to be married and have a young son, Kai. Parents of his students describe him as a ‘nice man who is very quiet and timid’.
“The way he is connected to all of this is what worries me,” one mother added.
The crime scene at Lion’s Academy on Daking Street has been sealed off and firefighters have covered the windows of the martial arts studio.

It is believed the black plastic was added to all windows facing the main street to hide the eerie scene in the studio from bystanders.
Forensic officers were also seen searching an alley at the side of the academy building, where locals said they had been told a body had been found.
At the Baulkham Hills address, a detective ran out of a car and ran into the driveway, under police tape and onto the crime scene at around 3.15pm.
The mansion’s front window was also smashed, with broken glass sprayed onto the exterior concrete.
The State Crime Commando Homicide Squad has now taken over the investigation, a NSW Police statement said.
