The Eugene Police Department said officers responded to a report of a physical dispute around 10:24 p.m. local time Friday night.
Officers arrived to find Bryan sitting outside a residence while the victim, 27, was at a nearby apartment, according to the police.
American actor Zachery Ty Bryan has been taken into custody over three charges, one of which involved him allegedly strangling his girlfriend. "The two have been in a relationship", police wrote in the arrest report.
The woman, who has not been identified, declined medical treatment. He grinned for his mugshot, which was released by the sheriff's office.
The 39-year-old now faces charges of strangulation and assault.
Bryan played Brad Taylor, the oldest son of Tim "The Tool Man" Taylor, the character played by Tim Allen on the popular sitcom, which ran 1991-1999. He has also appeared in Fast & The Furious: Tokyo Drift, Veronica Mars, The Game of Their Lives, Smallville, Cold Case and E.R.
