One police officer has died and another remains in surgery after being shot in a San Diego neighborhood, authorities said early Friday.
The San Diego Police Department gave an update on the officers on its Twitter account, but offered no additional details.
There was no immediate word on what touched off the violence, which occurred around 11 p.m. PDT Thursday in the southeastern part of town.
Police searched the area for suspects and urged residents to stay indoors.
Video footage showed officers out in force with numerous squad cars with emergency lights flashing lining a street, officers on foot, and a helicopter buzz overhead.
Police spokesmen did not immediately return calls for further comment, but the department said in a Twitter posting that one suspect was in custody and other possible suspects were being sought.
The shooting comes with law officers around the country on alert following the killing of officers in Dallas and Baton Rouge, Louisiana, this month.
