Oakland police on Tuesday had arrested five people - at least two with gang ties - in connection with an undercover police officer being shot in the arm on Monday as he was on a stakeout for a separate shooting.
Four were arrested Tuesday just before 11 a.m., just after Police Chief Howard Jordan was holding a news conference on the topic. Another person was arrested earlier at an apartment late Monday. Several guns were seized as well.
An NBC Bay Area photographer captured some of the arrests shown in the video above.
Jordan said that several suspects were suspected of being involved in shooting an an undercover detective who was sitting in a car in the 1700 block of Seminary Avenue about 6:22 p.m.
``They intended to assault and injure him,'' Jordan told reporters at a news conference. ``These are very dangerous people who will shoot at other people for no reason.''
The officer was in the neighborhood investigating a shooting in the 5900 block of Foothill Boulevard on Sunday that left a man with life-threatening injuries, police said.
The officer was shot in the arm and was back at home on Tuesday. The shooting sparked a massive hunt in East Oakland near the Oakland Coliseum.
The violence comes before a big meeting Tuesday evening at Oakland City Hall. That's when council members are expected to formalize voting on spending $250,000 to hire William Bratton, a former Los Angeles police chief and New York City police commissioner, as a police consultant to the city.
Last time a subcommittee met on the issue on Jan. 16, there were vocal protests from some community members who don't approve of Bratton's controversial policies, including stopping and frisking suspects.
Still, Bratton is widely respected in many policing circles and has had major crime reduction rates in the cities he has worked in. And at least one Oakland resident told NBC Bay area on Tuesday that she wants Bratton's help; she feels her civil rights are being violated by gangsters who infiltrate her neighborhood and limit her freedoms that way.
