A woman who went into cardiac arrest while undergoing a botched breast surgery at a Sydney beauty salon has died.

Jean Huang, 35, who managed the salon, underwent the procedure at the Medi Beauty Clinic in Chippendale on Wednesday afternoon and died at the Royal Prince Alfred Hospital on Friday.

A Chinese tourist, 33-year-old Jie Shao, administered a local anaesthetic and breast filler to Ms Huang, despite having no medical qualifications in Australia.

Ms Shao was charged with recklessly inflicting grievous bodily harm and using poison to endanger life.

Inquiries are continuing with a view to further legal action being considered, NSW Police said.

Ms Shao’s bail application was refused yesterday by magistrate Sharon Freund, who said police had a strong case against her.

Police said that Ms Shao had a plane ticket to leave Sydney for China.

“She has made a number of admissions in relation to local anaesthetics and breast fillers,” Ms Freund said.

The magistrate rejected assurances from the tourist’s legal aid solicitor that she had qualifications from the Canton (Guangdong) Medical University.

“These are very serious charges with a maximum of 10 years in jail,” she said.

“As Ms Shao is a tourist she is clearly a flight risk and risk to the community.

The police prosecutor said it was a strong case “with admissions on electronic recordings”.
