Emma Roberts was arrested on a domestic violence charge July 7, according to reports.
The incident took place in Canada, and the alleged victim was boyfriend Evan Peters.
Emma Roberts, Eric Roberts' daughter and Julia Roberts' niece, was taken into custody after someone called police to report a fight in Evan and Emma's hotel room.
Police found Evan with a bloody nose when they arrived, and Emma was arrested.
A law enforcement source tells TMZ that Evan also had a bite mark on him.
Emma, 22, was released hours later when Evan, 26, declined to press charges.
Sources close to Roberts say she and Evan were in fact hitting each other but only she was arrested since he had the obvious physical injuries.
The sources deny the bite mark detail and note that the couple is back together and both are working on the upcoming season of American Horror Story.
Here's hoping this Canadian horror story was a one-off.
