A bank teller tricked her relatives into handing over £68,000 under the pretence of investing it for them - but spent it on funding her lavish lifestyle instead.
Hien Ly, 40, committed the fraud while working as a teller at a bank on Greenwich High Street.
She told her three victims, all family members, that she was putting the money into "investments" and to purchase properties, the Metropolitan Police said.
She said that as she had a good position as an employee in the bank, she would get good rates and deals for them.
Ly lured her family in with their initial investments before demanding more and more money from them as time wore on.
Police Constable Stewart Bold, from the Economic Crime Team, said: "Ly used her position as a bank employee to fraudulently steal money.
"She was deemed a success by her family, which she used to gain their trust. Her family members invested their money with her believing it was not only safe but it was going to gain them profits in the future.
"Ly did not invest any of the money and despite supplying the victims with documents showing financial returns and property purchases, she had in fact used the money to fund her own lavish lifestyle. She has left the victims without savings and at a great financial loss through her greed and selfishness. This case is all the more shocking given she targeted her own family in the crime".
The victims lost a combined total of £68,499 in the series of frauds by Ly.
Ly was arrested at her workplace by officers on 20 May 2019 after being reported via Action Fraud.
She appeared at Woolwich Crown Court on Wednesday, and pleaded guilty to ten counts of fraud.
She will be sentenced at the same court on Tuesday 11, May.
