Police were called to the apartment of Bryan, 39, from the USA state of OR, on Friday (local time). They found Bryan, 39, sitting outside and his girlfriend, 27, at a neighboring apartment.
Cops said an investigation indicated that Bryan had taken the victim's phone as she attempted to call 911. "The two have been in a relationship", police wrote in the arrest report.
The victim declined medical assistance.
The actor grinned for his mugshot that has been obtained by TMZ. He has not yet entered a plea.
Bryan appeared in more than 200 episodes of "Home Improvement", a light comedy starring Tim Allen that ran throughout most of the 1990s.
While it's his best known role, Bryan also made appearances on hit shows including "Veronica Mars" and "Buffy the Vampire Slayer". It's been almost a decade since he appeared in a TV show or movie. He's listed as the executive producer for the science fiction thriller called Warning and Finding 52, which is a feature length documentary that is still in post-production. A potential representative for Bryan did not respond to a request for comment.
