A man believed to be the driver of a pickup truck seen running down three people in Northeast Portland earlier this year was arrested Thursday on suspicion of robbing an Oregon City drugstore.

Austin Keever-Nyberg, who’s accused of attempted first-degree assault in the Portland case, was one of two men arrested in an armed heist at a Rite Aid store, according to Oregon City police. No employees were hurt.

Police said Keever-Nyberg, 21, jumped the pharmacy counter Thursday night while armed with a knife, ordered employees to the ground, stole medication and left the store. He threatened another employee with the knife on his way out, according to police, and fled on foot toward nearby Main Street.

Officers set up a perimeter and initiated a police dog search, police said, and Keever-Nyberg eventually came back and ran to a car parked in the lot of the shopping center where the drugstore is located.

Police said the driver, 19-year-old Jacob Petersen, tried to make a getaway. Officers pinned the car, however, and took both men into custody without incident.

They recovered the medication and knife.

Records show both men are accused of first- and second-degree robbery, as well as unlawful use of a weapon, and are being held in the Clackamas County Jail.

He pleaded not guilty to three counts of attempted first-degree assault in the Portland case earlier this month. Video footage of the incident went viral.
