Chinese National Indicted for Running Sex Trafficking Operation in Boston

BOSTON - A New York woman has been indicted by a federal grand jury in Boston for allegedly running a sex trafficking operation out of several residential brothels located in Allston and Brighton, Mass.

Zengzeng Liu, a/k/a "Bella," 40, of Flushing, N.Y., was indicted on one count of knowingly persuading an individual to travel in interstate commerce to engage in prostitution and three counts of use of facilities of interstate or foreign commerce in aid of racketeering enterprises. The defendant was arrested yesterday in the Eastern District of New York and will appear in federal court in Boston on July 8, 2026 at 11 a.m.

According to the charging documents, beginning no later than August 2025, Liu, a Chinese national and lawful permanent resident of the United States, allegedly managed an international sex trafficking operation that recruited women - primarily foreign nationals from Japan, Vietnam, China and the Philippines - to travel to the Greater Boston area to engage in commercial sex acts for buyers at residential brothels in Allston and Brighton. Liu allegedly determined when and where the women would perform commercial sex acts, coordinated appointments with sex buyers, collected a commission from the proceeds and used foreign national middlemen to recruit women for the operation. It is further alleged that Liu used fraud, deceit and altered or forged documents to obtain and maintain apartments used as residential brothels.

As alleged, Liu advertised women on commercial sex advertising websites and directed prospective sex buyers to contact a phone number allegedly controlled by Liu. During undercover communications, Liu allegedly negotiated prices for commercial sex acts, directed buyers to the brothel locations and, in later communications, required prospective buyers to undergo a vetting process by providing identifying information, including photographs of work identification, before appointments would be arranged.

According to court documents, victims consistently described receiving instructions through the WeChat messaging application from a "female boss" they knew as "Bella," whom they identified as the organizer of their appointments but had never met in person. Victims allegedly traveled through locations including New York, China, Canada and the Philippines before arriving in Boston to work for the operation. Victims further stated that they collected payments from sex buyers but expected only a portion of the proceeds, with the remaining funds allegedly collected by couriers and ultimately forwarded to Liu.

The court documents describe that during searches of the Allston brothel location, law enforcement encountered women from Japan who had recently arrived in Boston and reported performing commercial sex acts for several days. It is further alleged that nearly $35,000 in cash was recovered from an Allston location, along with condoms, lubrication, surveillance cameras and cellular telephones. Surveillance footage from the Allston location also allegedly captured dozens of suspected sex buyers entering and leaving the apartment over multiple weekends, with the location allegedly generating tens of thousands of dollars in revenue during those periods.

According to court documents, during a search of the Brighton brothel location, law enforcement encountered women from Japan and Vietnam who reported that they had been engaging in commercial sex acts for several days after arriving at the apartment and were not permitted to leave the location. One victim allegedly displayed bruising on her knees, legs and feet and reported sustaining those injuries while performing commercial sex acts for sex buyers. Law enforcement allegedly recovered nearly $70,000 in cash from the Brighton location.

The charging documents further allege that financial records and other evidence revealed Liu used a Women, Infants, and Children (WIC) nutrition benefits card to purchase groceries while she was operating the commercial sex business.

In total, approximately $105,000 in cash was seized during the investigation. Based on surveillance, financial records and other evidence, it is estimated that Liu's sex trafficking operation allegedly generated hundreds of thousands of dollars in proceeds over the last 11 months.
