Four young girls were injured by a knife-wielding man inside a home in Bensonhurst Sunday morning before responding officers shot him, according to NYPD Police Commissioner Jessica Tisch.

The commissioner said police received a 911 call from an 11-year-old who said that she and her siblings had been stabbed by her uncle. The girl did not know her address, so the 911 call center used her phone’s location to send units.

When they arrived at 1671 84th St., an uninjured child led them to a vestibule that faced two doors. Tisch says officers kicked down one of the doors after hearing screaming.

Inside the home, they encountered a man holding a meat cleaver and covered in blood.

Tisch says the officer ordered the man to drop the cleaver, but he refused and “advanced toward them.”

Officers fired seven rounds between them and “ended the threat.” The incident was capture on bodycam, which has not yet been released.

The four female victims inside the apartment were ages 16, 13, 11 and 8. All had serious slash and stab wounds but are expected to survive.

The accused slasher was identified as 49-year-old Longqian Chen. The relationship between the man and the children has not yet been confirmed, but police believe he was a family member. He was taken to Maimonides Medical Center in critical condition.

Tisch said the man's family mentioned that he has a history of mental illness.

Two knives were recovered inside the apartment.

News 12 spoke with long-time residents like George Jarama, who said it was a horror scene.

“Young girl, her whole body, a lot of blood,” Jarama said.

Other residents like Humberto Huerta said he’s still in disbelief.

“I was really shocked. Nothing like that ever happens here. I’ve lived here for 10 years since I was young,” Huerta said.
