Super Junior’s Leeteuk’s April Fool’s Day prank has gotten out of hand.

On April 1st, Leeteuk posted his phone number without the last three digits on Twitter. At this, his fans guessed that the last digits of his phone number would be “1004” as his Twitter ID was “special1004.”

However, the last four digits of Leeteuk's phone number weren't “1004.” A person then uploaded a screenshot of the call log of the real owner of the “1004” and wrote, “From the early morning, my friend got several calls, even from foreign countries. Because of this, he couldn’t sleep at all.”

The victim and his friend tweeted Leeteuk to solve this problem, but Leeteuk just deleted his original tweet. Leeteuk tweeted again, “Don't be fooled by fake numbers. Just call my number here”, and revealed his real phone number.

However, the victim and the friend were not happy with Leeteuk's action and wrote, “My friend was really annoyed because of him. I guess he should apologize first. My friend is still getting phone calls from people he doesn’t know.”
