Towel guy Jung Yong Hwa opened his story that he had been locked up at the police station overnight.
"We were performing on the street, we were regarded as illegal aliens, caught by Japanese police.
We've never experienced that kind of thing in Korea, so we were knocked.
It happened last (2009) summer, we CNBLUE were doing street performance in Tokyo.
At that time, none of us was having passport. We were in confusion, we couldn't speak Japanese.
Japanese police thought we were suspicious, so they took us.
I worried that we could be banished. I contacted to the office, showed them our passport later.
We got free the next morning. The lockup cell was warm and clean, we didn't suffer at all. (laugh)
We just made an unforgettable memory."
CNBLUE was doing their activities in Japan as indie band preparing debut in Korea.
They performed more than 100 street lives to master stage sense.
After the lead vocal Jung Yong Hwa did Shin Woo of 'You are beautiful' they are taking big interest.
They make debut in Korea having showcase on Jan.14.
