AC/DC’s Phil Rudd has been arrested again in New Zealand, just over a week after being sentenced to eight months of home detention for threatening to kill a former employee.

The 61-year-old was arrested at his home in Tauranga on Saturday night, the New Zealand Herald reports. Police refused to comment on the nature of the arrest.

Rudd’s lawyer, Craig Tuck, confirmed in an email Sunday to the Associated Press that Rudd was due to appear in court on Monday for a bail application and that he’d spent an hour with the musician at the local police station where he’s being held ahead of that court appearance. Tuck did not say why his client had been arrested.

Rudd pleaded guilty in April to charges of threatening to kill a man who used to work for him and possession of methamphetamine and marijuana. At the sentencing hearing, Judge Thomas Ingram warned Rudd that he would go to prison if he breached the terms of his home detention, which includes 24-hour monitoring and prohibits him from taking any nonprescription drugs.

“I stone-cold guarantee that’s where you’ll end up,” Ingram told the drummer, according to the AP. “I’m not your headmaster, I’m not your father — I’m a judge.”
