Can you find Leeteuk?

Seems like Super Junior leader is trying out a hunting game as he uploaded the photo below on his twitter account.

On September 7, he uploaded a photo which is taken with many random people around him. He wrote a caption, "Tiny smile, find Leeteuk. Where is he?"

Honestly speaking,i still can't find our leader,do you mind to tell other readers where is Lee Teuk?
