New York City police officers shot and killed a 54-year-old man Sunday afternoon after he advanced toward them with a large butcher knife inside a Lower East Side apartment building, according to department officials.

The incident occurred shortly after 4 p.m. at 126 Ludlow Street, where officers had been dispatched following multiple 911 calls reporting an assault in progress. What officers discovered upon arrival would lead to a fatal confrontation within minutes.

Upon entering the building, responding officers found a trail of blood leading up the staircase, NYPD Assistant Chief Melissa Eger reported during a news conference Sunday evening. The evidence suggested an active and potentially violent situation was unfolding within the residence.

As officers proceeded up the stairs to investigate, they encountered Wei Chan, 54, descending the staircase while armed with what police characterized as a large butcher knife. According to the preliminary account provided by department officials, Chan advanced toward the officers despite their presence.

The circumstances that led to the officers discharging their weapons remain under investigation, though the department has confirmed that Chan was armed and moving toward law enforcement personnel when the shooting occurred.

The incident adds to ongoing discussions about police encounters with armed individuals and the split-second decisions officers must make when confronted with potential threats. The presence of multiple 911 calls and a blood trail suggests officers entered an already volatile situation with limited information about what they would face.

Assistant Chief Eger’s briefing provided the essential facts as they were known Sunday evening, though many questions remain about the sequence of events that preceded the 911 calls and what occurred between Chan and any potential victims before police arrival.

The investigation into the shooting will proceed according to standard protocols for officer-involved incidents. Such reviews typically examine whether proper procedures were followed, whether alternative methods of de-escalation were possible, and whether the use of deadly force was justified under the circumstances.

The Lower East Side neighborhood where the incident occurred has undergone significant changes in recent decades, though violent crime remains a concern for residents and city officials alike. This incident serves as a reminder of the unpredictable and dangerous situations law enforcement officers routinely face when responding to emergency calls.

The department has not released information about potential victims related to the initial assault calls or provided details about Chan’s background or what may have precipitated the violence that prompted neighbors to contact emergency services.

As this investigation continues, more information is expected to emerge about the full sequence of events that led to this fatal encounter between police and an armed individual in a Manhattan apartment building.
