AC/DC drummer Phil Rudd has pleaded guilty to charges of threatening to kill a former employee and possession of methamphetamine and marijuana, this according to various news reports. Rudd had originally pleaded not guilty to those charges last year.

According to The New Zealand Herald, however, Rudd will appear in court for sentencing on June 26, “when his lawyer will challenge conviction.”

Representatives for AC/DC had no comment when contacted by EW. Last year, the band’s guitarist, Angus Young, told The Huffington Post the charges against Rudd came as a “big shock,” but that AC/DC had “issues” with the drummer before.

“When we were recording, it was quite difficult to just get him in the studio,” Young said. “When we were in London when we were starting up to do the video shoot and stuff and it was the same then. He didn’t show, you know? That’s something we’ve got to resolve. Phil’s got to sort himself out.”

In December of last year, however, Rudd said he wanted to rejoin AC/DC as soon as possible.

“I’m going back to work with AC/DC and I don’t care who likes it or who doesn’t,” Rudd told New Zealand’s One News (via The Guardian). “I want my job back and I want my reputation back.”

Rudd did not perform with AC/DC during the band’s headlining slots at the last two weekends of Coachella, nor when the group played at this year’s Grammy awards ceremony. (Onetime drummer Chris Slade filled in for Rudd during those appearances.)
