A gang of fraudsters has been convicted of stealing millions of pounds.

Eleven people have been convicted for their roles in a large-scale "diversion fraud" scam using hacking software.

During a six-month trial at Blackfriars Crown Court, eleven people were convicted of crimes related to the scam - five of which are from Loughton or Buckhurst Hill.

Bonaventure Sunday Chukwuka, 41, of Roding Gardens in Loughton was found guilty of conspiracy to commit fraud by false representation, and conspiracy to conceal/transfer criminal property (money laundering).

Chukwuka was also found guilty of possession of a prohibited item (a phone) in prison.

Emmanuel Chike Chukwuka, 27, of Roding Gardens, Loughton was found guilty of conspiracy to commit fraud, and he was found not guilty of conspiracy to money launder.

Queen Chukwuka, 32, of Roding Gardens in Loughton was found guilty of acquiring or possessing criminal property.

Andrew Chike Chukwu, 35, of River Road, Buckhurst Hill was found guilty of conspiracy to commit fraud by false representation and conspiracy to conceal or transfer criminal property

Grace Plange Chukwu, 39, of River Road in Buckhurst Hill was found guilty of acquiring or possessing criminal property.

Ionut Relu Muresan, 34, of Long Deacon Road in Chingford pleaded guilty to conspiracy to commit fraud and conspiracy to money launder.

Mohammed Rahman, 31, of Garnies Close in Peckham was found guilty of conspiracy to commit fraud by false representation and conspiracy to conceal/transfer criminal property.

Gheorghe Alexandru Scurtu, 20, of Ladysmith Road in West Ham pleaded guilty to conspiracy to commit fraud and conspiracy to money launder.

All of the convicted criminals will be sentenced at the same court on a date to be confirmed.

During the trial, the court heard that Bonaventure Chukwuka led an organised criminal gang that targeted businesses and individuals by hacking into their email accounts and stealing large sums of money.

Officers from the Met’s Falcon Fraud Squad led the investigation.

Detectives identified a total of 228 separate frauds, committed between 2014 and 2018 totalling £10,112,312.54.

A total of 69 victims provided evidence during the trial - many of whom have been unable to recover their losses.

Several victims were traced with the help of the National Fraud Intelligence Bureau whose Action Fraud service allows both domestic and overseas victims to report fraud online.

The gang used computer malware to intercept and steal the log-in details of email accounts belonging to businesses and private individuals worldwide, with the intent of identifying high-value financial transactions.

They then intercepted emails about these transactions and sent spoof emails, duping the victims into paying the funds into alternative UK-based ‘mule’ bank accounts controlled by the fraudsters, instead of the intended recipient.

Officers identified165 mule accounts opened with fake identification documents or bought from unscrupulous account holders, which were used to receive the proceeds of the diversion fraud, where the money was quickly transferred onto other accounts, some of which were untraceable.

The fraudsters also used the funds from mule accounts to buy and export thousands of pounds of baby milk to Nigeria, to launder the money.

One of the fraud victims was a small construction company with a small team of employees based in the south west of England.

It was defrauded out of nearly £13,000 by the group in 2017 and had to close as a result.

Bonaventure, Emmanuel and Christian Chukwuka were arrested on January 26, 2018 on suspicion of fraud and were charged the following day.

Abassi established a sham company and opened business bank accounts, one of which received £1.9m on behalf of the wider gang.

He was arrested at Heathrow airport on February 14, 2018 and pleaded guilty to conspiracy to launder money on November 2, 2018.

Zaman and Rahman sourced mule accounts.

Zaman was arrested at Gatwick Airport on April 4, 2018 and Rahman was arrested on April 11 last year.

Following the arrest of the Chukwuka brothers, Andrew Chike Chuwku was identified as a significant associate. He was arrested on 11 April 2018.

Queen Chukwuka and Grace Chukwu - the wives of Bonaventure and Andrew - received funds into their own personal bank accounts.

Officers will now begin confiscation proceedings under the Proceeds of Crime Act to try and recover the money stolen.

Detective Constable Chris Collins, of the Met's Falcon Fraud Squad, said: "This has been an exceptionally long trial and the convictions mark the end of a complex, protracted investigation carried out by the Met’s Falcon Fraud Squad.

"The evidence amassed by detectives and presented during the trial was comprehensive and pointed towards a large-scale, planned fraud operation where successful businesses and wealthy individuals were targeted and deceived by a convincing fraud which involved payments arranged between two parties being successfully diverted by this gang.

"I would like to thank the victims in this case for giving evidence. Their accounts undoubtedly helped the jury arrive at their guilty verdicts. They have shown themselves to be unscrupulous fraudsters who have not given a second thought to the misery their actions have inflicted.

"I hope this conviction sends a strong message to online fraudsters: even though you think you are committing fraud at your keyboard in privacy, we have the ways and means of tracing you and we will seek to bring you to justice.

"We would advise anyone conducting financial business by email to verify the bank account they are sending their money to, by contacting the intended recipient and taking precautions to ensure the money is going to the right place.”
