EXO's D.O. is back as a half lunatic, half genius. 

In his brand new Wed-Thurs drama series 'Bad Prosecutor', D.O. plays an uncontrollable, unpredictable prosecutor Jin Jung, a guy who'll do anything to catch his culprit. In the first teaser for the new series above, Jin Jung confidently states, "Do you know what I learned after working in this field? That if I want to catch criminals like you, I need to be vicious, I need to be cruel, and I need to smack you on the backside of your head harder." 

Also starring Lee Se Hee, Ha Joon, Lee Si Un, Kim Chang Wan, and more, 'Bad Prosecutor' is coming soon to KBS2 beginning on October 5 at 9:50 PM KST. While you wait, you can check out the drama's latest teaser trailer above, as well as its new poster, below!
