Bendtner was arrested for assault on a taxi driver as he was heading home after a night out.
Per Sky Sports News, he was arrested but not charged with any crime.
Bendtner released a statement on the situation, which said: "I've been involved in an extremely unfortunate and uncomfortable episode. I could not imagine in my wildest dreams that it should develop as it did.
"I'm extremely sad that the outcome became as unfortunate as it became. In this context, there are some people whom I would like to apologise to.
"To Rosenborg fans, I apologise that this has happened. From the start it has been a pleasure to play for Rosenborg's faithful fans, and I have had the honour of making them proud of myself and of the team.
"To the club: I'm sorry with all my heart that we are standing here today. Rosenborg has been more than a good club for me. It felt like a new home and a new family, as I needed a new start more than ever. It's been easier to be the person I want to be.
"To my dear team-mates, I apologise that this will steal focus at an important time, and I thank you for the understanding I have already received.
"Those people I have shared changing rooms with every day for a year and a half fortunately know that I'm not and never have been a fighter, but that I protect those I love - on and off the pitch."
