Five alleged gang members have been detained in the shooting of an undercover Oakland police officer following an overnight lockdown of a East Oakland neighborhood and a tense home-by-home search by SWAT officers, authorities said.

Oakland police spokeswoman Johnna Watson confirmed that five suspects -- all suspected gang members -- were in custody. One suspect was arrested Monday night, a second was detained early Tuesday and three more were detained during the neighborhood search.

Armed with search warrants, SWAT teams worked their way through local homes and apartment buildings in the neighborhood in the pre-dawn hours Tuesday looking for the suspects.

At around 11 a.m., officers escorted a handcuffed man out of one of the apartment complexes in the neighborhood.

Watson said police will continue to keep a presence in the area on Seminary Avenue between Harmon Avenue and E. 17th Street.

The wounded undercover officer was following up on a recent gang shooting connected to the area around the 1700 block of Seminary Avenue when three armed men confronted him at 6:22 p.m. Monday.

The officer was shot once in the arm and taken to a hospital. His wounds were not considered to be life threatening and he had been released from the hospital by early Tuesday, police said.

Police shut down the area around the shooting scene, deploying SWAT teams to search for the suspects and restricting access. An armored SWAT vehicle stood deployed in the middle of the street with an officer armed with an automatic rifle on top surveying the homes.

There was no estimated as to when the neighborhood lock down would be lifted.

Oakland police have asked residents in the area who may have seen something suspicious to call 911 or (510) 777-3211.
