A Houston federal court on Thursday sentenced a 40-year-old Nigerian national to 228 months in prison. This was for his role in a multimillion dollar romance scam and business email compromise ring. Federal prosecutors say the scheme stole more than $4 million from elderly Americans and small businesses.
Leslie Chinedu Mba pleaded guilty on 4 December 2025. The charges were for conspiracy to commit wire fraud and conspiracy to make false statements in immigration documents.
At sentencing, the court heard the scheme ran from April 2018 through December 2023. It involved actors inside the United States. Networks overseas hijacked corporate emails. They also engineered sham romantic relationships to extract money from victims.
How The Scheme Worked
Prosecutors say the operation combined two proven engines of fraud.
First, co-conspirators gained unauthorised access to business email accounts and redirected legitimate payments into bank accounts they controlled. Victims sending payments to suppliers or service providers were unknowingly sending funds to fraudsters.
Second, the network ran romance scams that targeted lonely and elderly people. These individuals were persuaded into trusting fictitious partners. They were then convinced to transfer funds. Mba and others acted as money mules opening or using accounts to collect and launder the proceeds.
The court record describes a layered operation. Overseas technicians and insiders would divert invoice payments. Local operatives then moved cash through US accounts.
In parallel, romance scams supplied a consistent stream of smaller transfers. These were highly damaging and often devastated the life savings of older victims.
The combined losses totalled about $4 million, the prosecutors said.
The Guilty Plea and The Sentence
At his plea on 4 December 2025, Mba admitted to conspiring to commit wire fraud. He also admitted to submitting false statements in immigration filings while attempting to remain in the United States.
U.S. District Judge David Hittner imposed 228 months in federal custody. The court noted that removal proceedings will follow once the sentence is served.
The U.S. Attorney for the Southern District of Texas described the crimes in stark terms. Romance scams are among the lowest forms of fraud because they prey on the lonely and vulnerable. They disproportionately victimize senior citizens.
The FBI’s Houston office highlighted the deliberate weaponisation of romantic trust. This practice is particularly disturbing. The office vowed continued action against fraud networks.
Co-conspirators and Earlier Sentences
Federal filings show four other Houston residents pleaded guilty in the case. Grace Morisho, Rodgers Kadikilo and Kristin Smith received prison sentences ranging from 15 to 25 months.
A fourth defendant, Alexandra Golovko, was given five years’ probation.
Prosecutors say all were linked to the same web of business email compromise activity and money-mule operations.
Why The Case Matters
This prosecution lays bare a pattern investigators have warned about for years. Business email compromise schemes are lucrative and scalable.
Romance scams can have a lower value per victim. However, they inflict acute psychological harm on older people. They also cause financial harm on these individuals who are less likely to recover losses.
The hybrid model used here amplified both reach and returns for the conspirators.
For law enforcement the case is also a reminder of the cross border nature of modern fraud. Technical operators overseas can initiate attacks with little risk.
Networks that recruit money mules in the United States convert stolen funds into spendable cash.
Breaking those chains requires cooperation between corporate victims, banks, local investigators and federal agencies.
The Immigration Angle
Prosecutors say Mba attempted to regularise his status through multiple fraudulent marriages. His earlier application was denied, and he had been ordered removed.
The court found that he engaged in deception to remain in the United States. At the same time, he was running schemes that preyed on American citizens and businesses.
That duality drew sharp language from the U.S. Attorney. The attorney said the conspirators sought to remain here under false pretences. They were exploiting the trust that underpins the economy.
Lessons For Victims and Financial Institutions
Investigators and victim advocates offer a short checklist that would have reduced harm in many of these cases.
Businesses must adopt multi factor verification for payment changes and train staff to confirm transfer instructions by voice.
Banks should harden controls around account openings and unusual wire activity.
For individuals, especially older people, any romantic partner who asks for money or secrecy is almost always a red flag.
Prevention also requires public education. Romance scams flourish in the dark between loneliness and distrust of institutions.
Clear, widely distributed warnings are essential. Simple reporting channels can reduce the pool of vulnerable targets. They also increase the odds of early detection.
What This Means For Nigeria and the Diaspora
Every high profile prosecution of a national abroad risks a political and reputational blow for the home country. That said the crimes here were committed by a small network operating overseas and in Houston.
Nigerian authorities and diaspora organisations routinely condemn fraud and cooperate with foreign law enforcement when asked.
The larger burden is on receiving countries and financial intermediaries. They must stop illicit flows. They also need to minimize the space where money mule networks can thrive.
Closing Notes
Leslie Chinedu Mba will remain in custody pending transfer to a Federal Bureau of Prisons facility. After serving his sentence he faces deportation.
The case is being prosecuted by the U.S. Attorney’s Office for the Southern District of Texas. The FBI is leading the investigative work with assistance from the Houston Police Department.
