Updated, 3:50 p.m. with additional information about school lockdown.

The Portland Police Bureau's Gang Enforcement Team is responding to a report of a drive-by shooting at North Willis Boulevard and Newman Avenue.

At 2:37 p.m. Wednesday, North Precinct officers responded to the area and found evidence of gunfire but did not see any property damage or gunshot victims, police said in a news release.

Mary Becker, a resident in the area, said she heard about five pops. She said she hears shots fired in the neighborhood every few months.

There was no immediate information on a suspect.

Cesar Chavez School, a K-8 at 5103 N. Willis Blvd., was placed under lockdown shortly after the shooting was reported, said Christine Miles, a spokeswoman for Portland Public Schools.

Miles said she was alerted by the district's school security personnel about 2:45 p.m., just as students were transitioning from classes into after-school programs, and again around 3:30 p.m. after the lockdown had been lifted.
