Police were only responding to priority 1 and priority 2 calls, which are for incidents in which a life may be in immediate danger or with a potential for physical injury, as well as major property crimes.
Officers were not responding to other incidents, such as any crime in progress that doesn't pose an immediate danger to persons or property.
On Monday morning, police responded to reports of multiple armed carjackings in northern Portland that resulted in one victim being shot. Officers fatally shot the suspect when they arrived at the scene.
The Portland Police Department said in January that it is facing "critical" staffing shortages "due to budget cuts, retirements and separations, and the backlog of needed training for new officers caused by the pandemic."
Last year, 55 officers retired and another 29 separated from the department, leaving 855 sworn members on the force.
After cutting the police budget by $15 million in June 2020 amid calls to defund the police, the Portland City Council voted last month to bump law enforcement's funds by $5.2 million.
The $5.2 million will be used to hire 200 sworn officers and 100 unarmed community safety officers over the next three years.
Portland has already seen a record number of 72 homicides this year.
Mayor Ted Wheeler lamented the state of Portland last month as he advocated for the $5.2 million bump.
"Many Portlanders no longer feel safe in their city," Wheeler said at a news conference.
"Business owners have closed up shop for fear of doing business in high-risk areas. Commuters fear for their safety, whether taking public transport or going by foot. Parents are scared to let their children play outside."
