bt.dk reports Bendtner, who is on-loan from Arsenal, was arrested Saturday night around 2am after driving the wrong way up the Strand in Copenhagen.
It seems he also failed a breath test after going out with an old friend to each sushi and visit a sports bar, according to his advisor Jesper Lynghus.
"Dear friends, I was booked for a mild case of drink-driving last night," wrote Bendtner on Twitter.
"It was a quiet night, but I am very very sorry to all my friends and fans. It is not ok to drink and drive. I take full responsibility."
