Actress Marie Avgeropoulos, best known for her role on The CW’s “The 100,” faces jail time after being arraigned on one charge of misdemeanor domestic violence on Monday.

Avgeropoulos was arrested in Los Angeles last month after allegedly assaulting her boyfriend while on the freeway, hitting him in the neck, head and arm, according to the Los Angeles District Attorney’s office. The boyfriend had minor injuries and contacted the police, according to the DA’s office.

The Greek-Canadian was charged with “one count of injuring a spouse, cohabitant, boyfriend or child’s parent,” according to a statement from the DA’s office. If convicted, the 32-year-old actress faces up to 364 days in county jail.

The case remains under investigation by the Glendale Police Department.

Originally from Ontario, Canada, Avgeropoulos has also appeared in films “I Love You, Beth Cooper” and “Hunt to Kill,” along with having a recurring role on The CW’s “Cult.”
