NEW YORK (CBSNewYork) — An NYPD officer shot and wounded a knife-wielding man who had just stabbed his roommate in Cypress Hills, Brooklyn Sunday evening, police said.

As CBS2’s Erin Logan reported, Brooklyn North Borough Commander Assistant Chief Jeffrey Maddrey said preliminary information showed shortly before 9 p.m., police received a call about a physical fight at 110 Shepherd Ave.

As officers arrived, they encountered several men who were believed to be roommates. One of the two roommates reentered the apartment and came back with a knife, Maddrey said.

The man stabbed his roommate at least twice in both forearms, and began chasing his roommate as the roommate tried to run away, Maddrey said.

Officers ordered the suspect to drop the knife, and fired once just after the roommate was being stabbed, Maddrey said.

The man immediately fell and was rushed to Brookdale University Medical Center for observation, Maddrey said. His roommate was taken to Jamaica Hospital Medical Center, where his condition was reported to be stable, Maddrey said.

Police said the man who was shot police was not cooperative with orders, and they were concerned for the victim.

At least two or three officers were also taken to Jamaica Hospital for observation, Maddrey said. He said no officers are believed to be injured, but were hospitalized for their traumatic experience.

The knife was recovered, and police released a photo.

Maddrey said police have more witnesses to interview and more video to review as the investigation continues.
