Arriving deputies said that they encountered a black Escalade leaving the area, reportedly driven by Dahl.
They said that Dahl rammed a patrol car head-on before they turned on their emergency lights and drove off with another patrol car in pursuit.
Dahl would not stop for the deputy and slammed on his brakes several times trying to get the deputy to slam into the back of his Escalade, according to investigators.
Deputies said that Dahl later crashed head-on into a second patrol car before backing up his SUV and hitting the second car again.
According to deputies, Dahl was about to back up again when a third patrol car rammed the SUV and pinned it between two other patrol cars.
Deputies said they had to pull Dahl from the SUV and that he resisted arrest and fought with deputies.
They used a stun gun on Dahl, but said it had little effect.
Deputies were eventually able to take Dahl into custody and said that he suffered injuries in the struggle but is expected to recover.
"He did say, 'help me,' you know, 'I need help,'" said neighbor Becky Hughes, who witnessed the confrontation and arrest. "I heard him yell that."
Paramedics took three deputies to the hospital where they were treated and released.
The hospital released Dahl as well, and deputies then booked him into the Washington County Jail. On Sunday, Dahl posted bail and was released from jail.
The chase on Portland's west side wasn't the first police call involving Dahl on Thursday. Milwaukie police said they responded to a report of a disturbance at Dave's Killer Bread at 11:23 a.m. that day.
At the business, Dahl reportedly punched a display board and verbally intimidated employees before leaving the property, police said.
"He's having like a breakdown. He's sitting in his car, but he's been in and out," a 911 caller said. "He smashed a life-size cutout of himself."
Dahl drove off before officers arrived at the scene, and police determined no crimes were committed. They advised employees to call police if Dahl returned.
Dave's Killer Bread staff told police that Dahl wasn't authorized to be on the property, but the reason behind that is unclear at this point.
Stephen Houze, Dahl's attorney, addressed the entire episode Friday.
"It is apparent that this is a mental health crisis that has occurred, and it is our intention to do everything we can possibly do to help Dave," Houze said.
Dahl employs some ex-convicts at Dave's Killer Bread, which uses the tag line, "Just say no to bread on drugs." At last check in late 2012, Dave's Killer Bread employed some 300 people, a third of which were ex-cons. New York City-based Goode Partners took half ownership of the company late last year.
"The company and Dave's business partners are really concerned about Dave," said John Tucker, CEO of Dave's Killer Bread. "We hope that he's getting the help he needs, and we hope that anyone else involved is OK."
