Bieber's security team held the woman until police arrived and arrested her.
Laguna Beach police took to Twitter to address the alleged incident.
In a tweet, Laguna Beach police said, "Ok, here is a lesson on how not to get arrested. DO NOT party at night and into the next day till you get kicked out of a five star hotel. When you do get kicked out, DO NOT come right back again and "accidentally" walk into Justin Bieber's room with him still inside. #thebiebs."
