Two officers were stabbed in Medford Wednesday evening, police say.

The person who attacked the officers was shot and killed by one or more of the officers.

Both officers were taken to Stony Brook University Hospital. One of them was airlifted with a "significant" stab wound.

They are now listed in critical but stable condition.

The incident started at around 5 p.m. when a case worker was checking on two clients at an apartment on Birchwood Road.

One client became violent towards another.

Officers responded and the client that was acting violent attacked them.

"Officers made contact with the individual that was acting violent," said Suffolk Police Chief of Detectives John Rowan. "That individual produced a knife and subsequently stabbed two of our officers. Shots were fired by one or more of our officers resulting in the death of that individual."

The suspect who was killed by police still has not been identified.

A third officer suffered a minor injury in the attack. That officer was not stabbed but was also taken to Stony Brook University Hospital.

The names of the injured officers have not been released.

A neighbor says the apartment is owned by an independent living organization and that she has been having problems with one of the residents. She says her tires were slashed Wednesday morning and the organization sent a social worker after she complained.

The Suffolk PBA released a statement, saying, "We are thankful that the two Suffolk County Police Officers injured in today's incident are in critical but stable condition at this time. We are incredibly grateful for the outstanding care provided by Dr. Vosswinkel and the staff at Stony Brook University Medical Center. We ask that all Long Islanders keep our Officers in their thoughts and prayers, and God willing, they will make a full recovery from the horrific incident that took place earlier today."
