Rocker Nick Oliveri has been charged with five felonies following a lengthy standoff with police last month.
Cops swooped on the former Queens of the Stone Age star's Los Angeles home following reports of a domestic bust-up, but the musician refused to allow them into the property.
A special weapons and tactics (SWAT) team was called amid fears Oliveri had a high-powered rifle at the residence and the rocker eventually gave himself up. He was booked for felony domestic violence and released on $100,000 bail.
However, new court documents, obtained by TMZ.com, show Oliveri is facing further charges after police allegedly discovered a fully-loaded rifle and cocaine and methamphetamines in his home.
The rocker is charged with two counts of possession of a controlled substance with a firearm, two counts of possession of a controlled substance, and one misdemeanor count of resisting, obstructing or delaying a peace officer.
If convicted, the 39-year-old musician faces up to 15 years in prison.
