16 charged in sweeping Houston-based multimillion-dollar illegal gambling, money laundering conspiracy

HOUSTON – Several Houston-area residents were taken into custody April 2 on various charges including conspiracy, operating illegal game rooms, bribery, and money laundering following one of the largest law enforcement operations in East Texas history.

The operation was led by U.S. Immigration and Customs Enforcement with assistance from IRS Criminal Investigation; the Houston Police Department; FBI; High Intensity Drug Trafficking Areas Program; Harris County Constable’s Office – Precinct One; Harris County District Attorney’s Office; Bureau of Alcohol, Tobacco, Firearms and Explosives; and Drug Enforcement Administration.

In addition to those indicted in the scheme, authorities also arrested 31 illegal aliens on various immigration and firearms charges. One of those included an illegal alien who allegedly assaulted a law enforcement officer.

The indictment, returned March 26 and unsealed upon the arrests, alleges Nizar Ali, 61, of Richmond, and others allegedly conspired to own, operate or assist in the operation of illegal game rooms. All also conspired to conduct financial transactions to conceal and disguise the nature and source of the proceeds of the illegal gambling business, which totaled more than $22 million, according to the charges.

More than 700 law enforcement officers from 18 agencies served a total of 45 search and 40 seizure warrants at locations throughout Houston and the surrounding area. The locations included 30 illegal game rooms with names such as El Portal and Yellow Building.

During the operation, authorities recovered more than $11 million in seized cash and bank accounts, as well as $5 million in property and vehicles, 2,000 slot machines, 100 Rolex watches and eight firearms. Law enforcement also seized approximately $6.5 million from bank accounts and other financial institutions pursuant to the court-issued warrants.

In addition to Ali, others taken into custody include Naeem Ali, 33, and Amer Khan, 68, both of Richmond; Ishan Dhuka, 33, and Sahil Karovalia, 32, both of Rosenberg; Sarfarez Maredia, 38, and Shoaib Maredia, 40, both of Sugar Land; Yolanda Figueroa, 40, of Pasadena; Viviana Alvarado, 45, of LaPorte; and Anabel Eloisa Guevarra, 46, Precela Solis, 27, Maria Delarosa, 53, Claudia Calderon, 37, and Lucia Hernandez, 34, all of Houston.

Two others – Sayed Ali, 59, of Richmond, and Stephanie Huerta, 35, of Houston – are considered fugitives and warrants remain outstanding for their arrests.

All are charged with conspiracy, operating an illegal gambling business and interstate travel in aid of racketeering which each carry possible prison terms of five years as well as conspiracy to commit money laundering which has a maximum 20-year possible prison term. Ali is also charged with 32 counts of federal program bribery for allegedly paying more than $500,000 to an undercover officer in an attempt to protect the illicit game rooms from law enforcement intervention. If convicted, he faces up to 10 more years in prison on each count. With the exception of the money laundering charge, which has the possibility of a $500,000 maximum fine or twice the value of the property involved, the remaining counts carry a maximum $250,000 potential fine.

Other agencies who provided support to the operation included U.S. Customs and Border Protection, Harris and Montgomery Counties’ sheriff offices, the Houston Fire Department, Texas Attorney General’s Office, Texas Department of Public Safety and Baytown and Pasadena police departments.

Assistant U.S. Attorneys S. Mark McIntyre, John Marck and Carolyn Ferko are prosecuting the case. Assistant U.S. Attorneys Brandon Fyffe and Tyler Foster are handling the seizure and forfeiture of assets.

An indictment is a formal accusation of criminal conduct, not evidence. A defendant is presumed innocent unless convicted through due process of law.
