MANCHESTER, N.H. (MyKeeneNow) A New York man at the center of a sweeping scam operation that defrauded victims in New Hampshire and beyond has pleaded guilty to multiple charges tied to the scheme.

Oumar Diallo, 22, of the Bronx, appeared in court Thursday and admitted guilt to six charges across three separate cases, including theft by deception and receiving stolen property. Prosecutors say Diallo acted as a courier, picking up large sums of cash from victims who believed they were posting bail for loved ones.

In one striking example, a New Hampshire resident was told their son had been arrested in a fatal crash involving a pregnant woman. They were instructed to hand over thousands in cash. Unbeknownst to them, it was all part of a sophisticated ruse.

During his plea hearing, Diallo, using an interpreter, listened as the judge explained the court process and the implications of his plea. Sentencing has been scheduled for July 18.

Authorities believe Diallo played a key role in a broader, nationwide fraud operation that swindled over $200,000 from unsuspecting victims. His arrest followed an intensive investigation that began more than a year ago in New Boston,

Back in April 2024, a New Boston woman was scammed out of $24,000 after receiving a call from someone claiming to be her grandson’s attorney. She was told he had been arrested after a serious car accident and needed bail money immediately.

She was convinced the caller was her grandson and suspects voice-cloning technology might have been used. Authorities say similar scams often exploit personal data gathered from social media and online databases.

The woman handed over the cash—but not before snapping a photo of the vehicle Diallo was driving.

That photo proved pivotal as evidence. Law enforcement was able to track rental agreements and determine who that driver was. The driver matched the description of the man who came to the residence, and he was arrested.

Investigators linked Diallo to similar scams in at least five other New Hampshire towns, including Keene and Jaffrey, as well as communities in Maine, Massachusetts, and even as far west as Nevada and California.

He was eventually arrested in Redondo Beach, Calif., on April 27, 2024, and extradited to New Hampshire.

It’s believed he did not act alone.

Since Diallo’s arrest, additional victims have come forward. Police are urging anyone who suspects they’ve been targeted by similar schemes to contact local authorities.
