A New York City police officer who suffered a serious head wound after being attacked by a hatchet-wielding man remains in critical but stable condition.

Police say another officer who was hit in the back of the head is in stable condition on Friday.

The attacker was shot and killed by police.

Authorities say security videotape showed the man attacking four rookie NYPD officers on Thursday in a busy commercial district in Queens.

Police say the suspect was seen on a street corner crouching down to pull the hatchet out of backpack before he charged the officers and began swinging the hatchet with a two-handed grip.
