A New Orleans police officer was shot and killed early Friday, October 13, according to the NOPD.
Harrison also said one or two of the officers returned fire, possibly hitting the suspect.
Paramedics took the officer to University Medical Center, and he died there, Harrison said.
The suspect was detained after a standoff in a nearby apartment.
New Orleans Police Chief Michael Harrison told reporters that gunshots were fired at four officers shortly after midnight local time (1 a.m. ET).
Superintendent Harrison declined to identify the deceased officer at this time.
Mayor Mitch Landrieu was also on the scene.
After police shot the man who opened fired at them, Harrison said, the wounded gunman fled into an apartment.
Negotiation teams were able to get the man to surrender peacefully.
The deceased officer's identity has not been released.
"Our department is grieving, our city is grieving and this family is grieving", said Harrison.
"Our worst nightmares have come to be", Landrieu said.
