Two arrests were made by special enforcement teams, including arresting a suspect with a $350,000 shooting-related warrant in the 1400 block of 73rd Avenue and a felon with a firearm in the 1400 block of 48th Avenue, police said.
Police also arrested a suspect after arriving at the scene of a shooting near the corner of 98th Avenue and Holly Street at 12:04 p.m.
As officers arrived, a group of people ran in multiple directions and police saw one of the runners was carrying a gun.
After chasing the suspect into a nearby yard, police set up a perimeter and the gunman surrendered to police. A gun was recovered from the suspect, police said.
That shooting is the most recent in a string of gun violence that left two dead and 15 injured in as many as 18 incidents reported since last Friday.
To address the pattern of violence, city officials toured some of the areas most affected by shootings on Tuesday to discuss various aspects of public safety and plans of action for reducing crime, police said.
Police said that Chief Howard Jordan and City Administrator Deanna Santana visited several of Oakland's hardest-hit neighborhoods with representatives from all city departments.
They discussed violence prevention, job growth, blight, street and sidewalk conditions, youth recreation opportunities and community outreach at each stop and plan to hold monthly meetings and future visits to evaluate progress, police said.
