PORTLAND, Ore. -- Detectives arrested a second suspect in a wilding spree of beatings and robberies that left several people hurt in North Portland earlier this month.

According Portland Sergeant Brian Schmautz, the crimes started when a driver pulled up next to a red pickup stopped in the middle of the road at the intersection on Northeast Columbia and 33rd around 4 a.m. August 12. That's when the four suspects started throwing things at the driver, then broke a windshield and took off.

After that, there were reports of random assaults on four more people and a robbery at a gas station on N. Interstate. That’s where the suspects were caught on surveillance tape.

The latest suspect was identified as 26-year-old Mack Parnell. Parnell was charged with assault, robbery and theft after his arrest Wednesday morning.
