A knife-wielding man who injured three people in a series of attacks at the Grand Central subway station in New York City was shot dead by police on Saturday, authorities said, adding that there is no link to terrorism.The suspect, identified as 44-year-old Anthony Griffen, carried out multiple stabbings shortly after arriving at the busy transit hub, prompting a swift response from the New York Police Department.According to police, Griffen boarded a 7 train at the Vernon Boulevard station in Queens on Saturday morning and reached Grand Central soon after. He first stabbed an elderly man on the platform before moving to the 4/5/6 line, where he slashed two more people.Officers responded to the incident shortly after 9:30 am. Two NYPD detectives on an overtime transit assignment encountered one of the injured victims while heading to the scene, officials said.During the confrontation, Griffen was acting erratically and claimed he was “Lucifer,” Police Commissioner Jessica Tisch said at a press conference.Police said the detectives ordered Griffen to drop the large knife he was carrying around 20 times. However, he advanced toward them with the blade extended, forcing one of the officers to open fire. Griffen was shot twice and later died.Authorities said Griffen had three prior arrests in New York City.The three victims sustained serious slashing injuries but are currently in stable condition at a hospital, police confirmed.New York City Mayor Zohran Mamdani said he had been briefed on the incident and praised the police response.“I’m grateful to the NYPD for their quick response and for preventing additional violence. The three victims were taken to the hospital and are thankfully in stable condition. The NYPD is conducting an internal investigation and will release body-worn camera footage, as it does in all incidents involving the discharge of an officer’s firearm,” Mamdani said in a statement.Police said an internal review of the shooting is underway, in line with standard procedure for incidents involving the discharge of a firearm by officers.
