Critically-acclaimed indie musician Kang Tae-gu on Wednesday apologized over allegations of abusing a former girlfriend in the past.

Kang, who won Best Album of the Year at the 2018 Korean Music Awards (KMA) last week, wrote on Facebook that he admits to the allegations and is sorry. The singer also announced that he will indefinitely suspend his music activities.

"I've been in a relationship with musician A for three-and-a-half years. I admit being involved in the incidents and want to apologize," Kang wrote. "I regret my foolish actions in the past," he added.

A female indie musician reported to be Kang's ex-girlfriend has accused him of physically and verbally abusing her in the past. Through her social media, the woman has also shared her experience of being forced to watch pornography and received repeated demands for sex after splitting up.

Kang debuted with his first full-length album, "Deul," in 2013. He won three awards at the annual KMA held last Wednesday, including the highly-coveted Best Album of the Year and Best Folk Album of the Year awards for his second studio album, "bleu."

In light of the "Me Too" movement sweeping across the nation, KMA officials are currently deliberating whether to revoke the awards won by Kang. (Yonhap)
