The two incidents were about 10 blocks apart and happened within 30 minutes.
The first shooting took place at about 10:15 p.m. on the 9100 block of International Boulevard; a man was shot in an apartment building.
Before police entered the apartment, they only knew that shots had been fired and had to proceed with caution.
"They went in, not certain whether or not the suspect was still on scene, so we had the residents stay in their location, then the officers went up and rescued and assisted the paramedics with getting treatment for the person who was shot," said Oakland police Lt. Demetrio Lozares.
A dozen people had to be evacuated from the complex. The shooting victim was taken to the hospital and is in stable condition.
The other incident took place at about 10:45 Monday night when an AC Transit bus that had just stopped to let off a passenger, was shot at four times on 100th Avenue and International Boulevard.
"Right after the passenger got off, two gunshots went into the bus, the driver started off and a couple more rounds were put into the bus. The driver just took off and drove," said Lt. Lozares.
The bus drove down International, where they found cops working the shooting at the apartment. Police said nobody was injured but they were unable to interview anyone on the bus because the passengers scattered immediately.
"Anytime you have something like this happen in Oakland it is very hanus and we take it very seriously," said Oakland police Officer Holly Joshi.
Tuesday morning, near the bus shooting scene, some Oakland residents talked about their concerns.
"I do feel kind of frightened about being on the bus because when I ride the bus with my daughter she likes to ride the window seat all the time. So yes that pretty much frightens me," said Oakland resident Michelle Johnson.
Others feel that it is just the way it is in this neighborhood, including the driver of an AC Transit bus.
"Why should I be afraid?" asked AC Transit driver Michelle Belt.
"It doesn't matter, because this is a crime neighborhood," said Oakland resident Jesse Webb.
"Look at where you're at, you're going to get shot at regardless out here, but that is AC Transit for you, it is cheap public transit," said Oakland resident Michael L.
"This time the citizens of Oakland are getting fed up and they are looking for our cooperation," said Joshi.
No arrests have been made in either case.
