Galaxy Express bassplayer and "Band Generation" finalist Lee Joo Hyun was arrested for smoking marijuana on Tuesday, according to the website allkpop.

The 36-year-old bassist and vocalist has reportedly been arrested for using the drug once before.

Galaxy Express recently made it to the final round of "Band Generation," a televised battle of the bands on the South Korean music television cable channel Mnet.

The show's producers are reportedly still deciding what to do about airing the Galaxy Express footage in light of Lee's marijuana arrest.

"After hearing the news today, the staff of 'Band Generation' are currently in discussion on what move to make concerning the pending broadcast of the final round," an Mnet spokesman said on Wednesday.

The "Band Generation" episode in question, scheduled to air July 9, also features the groups Daybreak and Romantic Punch, all battling it out for the title.

Back in April, Lee owned up to having a rebellious past in an interview with Seoul Magazine.

"I wonder if I've ever worked hard for anything other than music. I was literally living for music the whole six years [since this band started in 2006]," he said.

"Back in school, I was doing bad, bad things."

The singer also sounded off about the seemingly endless line of boy bands and girl groups that dominate the K-pop landscape.

"Because we pursue different things from K-pop artists [in Galaxy Express], the popularity of girl groups and boy bands does not have a big effect on us," Lee said.

"In fact, we're just paving our own road."

Although he admits the popularity of K-pop has allowed him a respite from questions regarding Korea's political tension between the nations of the north and south when he travels overseas.

"Years ago when I was visiting France, all people asked me about were North Korea, Kim Jung-il, and missile tests," said the Galaxy Express bassist.

"They thought Korea was at war and asked me if I was okay. But I don't get that now. K-pop is more popular than [former North Korean leader] Kim Il Sung now."

Lee also discussed his band's high-energy live show.

"I think all three have us [in Galaxy Express] were born with that energy," he said.

"Even [Kim] Hee Kwon, who is normally very quiet, pounds and beats drums like his arms are going to fall out when performing. I didn't even know he was like [onstage] that until we watched our video on YouTube."
