A Harrow woman has been handed a 14-month prison term, suspended for two years, after a "money mule gang tricked" victims into transferring money to criminals' accounts.
Nishma Bharadia, 29, of Taunton Way, Stanmore, was also give a three-month curfew and ordered to pay £5,140 in fines and costs after she, along with 10 other people, were convicted at Woolwich Crown Court of money laundering offences.
The charges related to a scam where people were tricked into changing a direct debit, standing order or bank transfer mandate by those purporting to be from an organisation or person to whom regular payments were made.
In total, the network of five men and six women received more than £1.7m into accounts between January 2011 and December 2013.
Police identified 17 victims - a mixture of companies and individuals - based in the UK, Sweden, Nigeria, Mauritius, France, Switzerland and the United States.
Detective Sergeant Kevin Jackson, of the Metropolitan Police’s criminal finance team, urged the public to check account details before transferring any money.
He said: "Members of the public and organisations need to be very careful when moving and transferring money.
“Many of the victims linked to this case were tricked into sending money to criminals' accounts after they were sent a spoof email with change of payment details.
"Always verify changes to financial arrangements with the organisation or person directly on the phone, or go via the company's main switchboard to check if an email is genuine.
"Trust your instincts and always check before transferring the money, because it will be extremely difficult to recover once you've sent it."
The criminal activity was uncovered after an investigation was launched in June 2013.
Officers had found money being quickly moved on through several accounts controlled by members of the criminal network in a process called layering.
The money was then finally withdrawn as large amounts of untraceable cash from branches or cash machines.
Further enquiries revealed that some of the bank accounts linked to the money laundering were set up in the name of sham companies.
