A woman posing as a cleaner allegedly helped orchestrate a brazen armed home invasion in Brooklyn last week — a daylight robbery that left a young couple shaken and neighbors questioning how safe their building really is.

According to the New York Police Department, the burglary unfolded Friday morning at an apartment building near Vandalia Avenue and Fountain Avenue in East New York.

Police say a woman knocked on the door of an apartment and claimed to be from a cleaning agency. When a couple in their 30s answered, the situation allegedly escalated in seconds. The woman and two male accomplices reportedly drew firearms and forced their way into the unit.

What followed was swift and calculated.

Investigators say the trio went directly to a bedroom, where they stole jewelry valued at approximately $118,000. They also took credit cards, wallets, and a purse, bringing the total value of the stolen property to an estimated $122,000.

Authorities said the suspects fled on foot down Fountain Avenue toward Seaview Avenue. No arrests have been made as of publication.

Police described the female suspect as wearing a black jacket, white T-shirt, black pants, a black hat, and black sneakers. One male suspect was described as wearing a dark jacket and dark hat. The third suspect reportedly wore a multicolored blue sweatshirt, dark pants, and black sneakers.

The boldness of the alleged ruse — using a fake cleaning service as a way to gain entry — has left residents unsettled.

“It makes you not trust anybody. It makes you not want to open your door to anybody,” neighbor Shawna Abram said. “It’s sad … honestly really sad.”

Another resident, Winston Hurley, questioned how the suspects gained access to the building in the first place.

“How did they get in building?” Hurley said. “I feel unsafe because we’ve been trying to tell these people they need security in these buildings.”

Security concerns appear to be at the forefront for many in the area. One neighbor, Jesus Rodriguez, said he received a Ring doorbell alert that may have captured an image of one of the suspects.

“Saw one individual with a hood on,” Rodriguez said. “In retrospect, people should be more aware when opening up a door. I’ve been guilty of that myself once or twice.”

Police have not said whether the suspects specifically targeted the couple or if the building was chosen at random. Investigators are reviewing surveillance footage from the building and nearby cameras as they attempt to track the trio’s movements.

The case underscores a growing concern about increasingly sophisticated home invasion tactics, where suspects rely on everyday disguises — delivery workers, maintenance staff, or cleaners — to lower a victim’s guard.

For residents in East New York, the incident has turned an ordinary knock at the door into something far more ominous.

As the suspects remain at large, police are urging anyone with information to come forward.

In the meantime, behind locked doors and buzzing intercoms, neighbors say they’re thinking twice before answering.
