Paulinus Okoronkwo ran a modest law practice out of Koreatown, Los Angeles, handling immigration paperwork, family disputes, and personal injury cases for clients who knew him simply as “Pollie.”

It was, by most appearances, an unremarkable American professional life for a 58-year-old dual citizen who had made his home in the quiet suburb of Rancho Cucamonga.

What his clients didn’t know, and what United States federal prosecutors spent years untangling, was that Okoronkwo was simultaneously serving as general manager of the upstream division of the Nigerian National Petroleum Corp., Nigeria’s state-owned oil company. And in October 2015, he received a wire transfer of $2,105,263 into his law firm’s trust account from a Swiss subsidiary of one of China’s largest energy conglomerates.

On Thursday, a federal judge sentenced Okoronkwo to 87 months in prison for what prosecutors described as a textbook international bribery and money laundering scheme, one that stretched from the oil fields of the Niger Delta to a $983,200 home purchase in Valencia, California.

The deal

The money came from Addax Petroleum, a Geneva-based subsidiary of Sinopec, the Chinese state-owned petroleum and petrochemical giant. Addax held drilling rights in Nigeria, rights that were, by 2015, in serious jeopardy following a dispute with the NNPC over financial terms.

According to US Attorney’s Office, Central District of California, Addax’s internal calculations projected losses running into the billions of dollars if the matter went the wrong way.

Enter Okoronkwo. As general manager of NNPC’s upstream division, he was in a position to influence exactly the kind of settlement Addax needed. He owed a fiduciary duty to the Nigerian government. He was, legally speaking, a public official.

Addax signed an engagement letter with his Los Angeles law firm, bearing a fake Lagos address, purportedly retaining him as a consultant to help negotiate a settlement with the NNPC. Prosecutors say the letter was a fabrication, and the $2.1 million wired to his Interest on Lawyers’ Trust Account was not a consulting fee. It was a bribe.

The Cover-Up

Getting money is one thing. Keeping it hidden is another.

To sanitise the paper trail, Addax falsely classified the payment as legal fees in its financial records, misled an external auditor about the transaction’s nature, and terminated executives who raised internal objections about its propriety. On Okoronkwo’s end, the use of an IOLTA, a type of account lawyers use to hold client funds, was designed to give the payment the veneer of legitimacy, obscuring that it was personal income.

Between February 2016 and 2018, Okoronkwo moved the funds through a shell entity called IPO Capital LLC, then spent them on family expenses, a car, and real estate. In November 2017, he used $983,200 of the bribery proceeds as a down payment on a house in Valencia. He did not report the $2.1 million on his 2015 federal income tax return.

The obstruction charge stemmed from a June 2022 interview with federal investigators, when Okoronkwo told agents he had not used any of the money to buy a house, a lie, and that the funds were client money, not income.

The reckoning

A federal jury convicted Okoronkwo in August 2025 after a four-day trial, finding him guilty on three counts of transactional money laundering, one count of tax evasion, and one count of obstruction of justice. United States District Judge John F. Walter imposed the 87-month sentence Thursday and ordered Okoronkwo to pay $923,824 in restitution to the IRS and forfeit nearly $1.04 million, the net proceeds from the sale of the Valencia home.

The State Bar of California suspended his law license in January 2026.

The case was investigated by the FBI and IRS Criminal Investigation, with assistance from the Justice Department’s Office of International Affairs. It was prosecuted by Assistant U.S. Attorneys Alexander B. Schwab, Nisha Chandran, and Alexander Su.

For Addax, whose parent Sinopec is one of the world’s largest energy companies by revenue, the episode adds to a broader pattern of scrutiny over how Chinese state-owned enterprises secure energy assets in Africa, a region where Beijing has invested hundreds of billions of dollars over the past two decades. Addax’s role in the scheme has not resulted in publicly announced charges against the company or its remaining executives. (BusinessDay)
