San Francisco police arrested a 42-year-old woman, Diana Peng, early on Friday, November 6, while executing a search warrant at a residence on the 200 block of 32nd Avenue in the city's Richmond District, the San Francisco Police Department said in a release (case #26-139). Officers arrested Peng at 7:30 a.m. and booked her at San Francisco County Jail, police said.

Police said Peng was arrested for alleged fraud charges, for allegedly being a felon in possession of a firearm and a felon in possession of ammunition, and on alleged narcotics charges, alleged driving without a licence and alleged improper care of animals. The release lists the charges in those general terms and does not publish a fuller charge sheet, a court date or any detail about what officers found during the search. An arrest is an allegation, not a conviction, and the charges will be tested in court.

Police: the investigation is still open

'Although an arrest has been made, this remains an open and active investigation,' the department said. Anyone with information is asked to contact the SFPD at 1-415-575-4444, and callers may remain anonymous, police said. The department's Richmond Station number listed in the release is 1-415-666-8000. Police have not said in the release whether they are seeking any other person in connection with the criminal investigation, and they have not described the firearm, ammunition, narcotics or animals referred to in the charge list.

The background: a city lawsuit over an alleged Sea Cliff deed scheme

Peng's name was already before a San Francisco court in a separate civil case. On September 11, 2026, City Attorney David Chiu filed a lawsuit on behalf of the People of the State of California against Brandon Aadee and Diana Peng, alleging what his office described as a deliberate and sustained scheme to unlawfully take ownership of a Sea Cliff home using forged and fraudulently altered property deeds. The home at the centre of that civil case is at 250 32nd Avenue — the same street and block as the address where police served the search warrant on November 6. The police release does not state that Friday's arrest arises from the civil case, and Awaaz Punjab is not reporting that it does; the civil allegations are background that readers need to understand why Peng's name was already in public court filings, and they remain allegations to be proved in that case.

City Attorney Chiu said in the September announcement: 'Defendants are effectively trying to steal a house and sell it to make millions in profit. Several notaries have said defendants forged their signatures or illegally altered the deeds. That is fraud, and they are trying to profit off that crime. This unfair business practice undermines the legal real estate market and wastes scarce government resources. We are asking the court to declare these deeds invalid and stop this fraudulent scheme.' Assessor-Recorder Joaquín Torres said: 'Real estate fraud is a serious matter for law enforcement and the courts and I'm glad to see that the City Attorney is helping move it there so this matter may be resolved for the public's benefit.'

What the city alleges happened to the house

According to the City Attorney's office, the property at 250 32nd Avenue was believed between 2013 and 2025 to be owned by Wei Wang and her husband. At some point Wang left the country and stopped paying property taxes on the home, the office said, and the owners owe the city more than $320,000 in back taxes; Treasurer José Cisneros has initiated a tax auction process to sell the house and recover the taxes owed. In July 2025, the lawsuit alleges, Aadee recorded a deed that purportedly transferred the property from Wang to Aadee. After that first deed, Aadee and Peng allegedly transferred the property back and forth between themselves over thirteen months, recording eight deeds in all, at least five of which the city says contain forged notary signatures, fraudulent stamps or attestations altered after notarisation. Multiple notaries have confirmed their signatures or seals were forged or misused, the office said, and in some cases notaries reported that documents from legitimate remote notarizations for Peng were later changed to falsely show Aadee had personally appeared before them when he had not.

The city also alleges that at various times Aadee and Peng claimed on the deeds that a transfer was made pursuant to a 'divorce' or 'dissolution of marriage,' although there is no record of the two ever being married; that both defendants have criminal histories including fraud-related offences, in the city's account; and that the defendants attempted to sell the home below market value in a quick transaction before the alleged fraud could be detected, which the city says indicates they never intended to live in the home and were seeking a multi-million-dollar windfall from a home they never owned. Those are the city's allegations in a civil complaint, not findings by a court.

Why a deed case matters beyond one house

Property deeds are the public record on which every home sale, mortgage and inheritance in San Francisco rests. The City Attorney's office argues that the alleged conduct violates California's Unfair Competition Law, which prohibits unlawful, unfair and fraudulent business practices, and it is seeking cancellation and invalidation of all the deeds recorded during the thirteen-month period, along with injunctive relief to prevent further unlawful activity. For homeowners — including immigrant families in the Richmond District and across the Bay Area who may hold property while relatives live abroad, as the city says happened here when an owner left the country and taxes went unpaid — the case is a reminder in the city's telling of why tax notices, title records and unexpected filings against a property need attention even when a house sits empty.

What happens next

On the criminal side, Peng was booked at San Francisco County Jail, and the SFPD investigation remains open and active, with police asking anyone with information to call 1-415-575-4444. The release gives no arraignment or court date, and no statement from Peng or a lawyer for her was included in the police release or the city announcement cited here. On the civil side, the Superior Court case will decide whether the eight deeds are declared invalid and whether the injunction the city seeks is granted, and the separate tax auction process the treasurer initiated over more than $320,000 in back taxes forms part of the property's future as well. Awaaz Punjab will update this story when police publish any fuller charge sheet or when either court sets its next step.
