According to a report by TMZ, Oliveri’s girlfriend told police she went to his house to collect her belongings following an argument the previous day in which the bassist struck her. This led to another serious confrontation that resulted in Oliveri locking them both inside his duplex.
Police arrived, responding to a 911 call from a neighbor, and Oliveri refused to let them in or let his girlfriend leave. A S.W.A.T. team was called in, which led to tense negotiations resulting in the girlfriend being set free after two hours, and Oliveri turning himself in two hours after that. Once they were inside the house, police discovered that Oliveri had a fully loaded high-powered rifle in his possession.
Oliveri has since been released after posting $100,000 bail.
