Mathew Rosengart, Spears' attorney, confirms to PEOPLE that Alexander, 40, is "incarcerated" and is under an Emergency Protective Order. "This was an outrageous security breach, which I am livid about, but fortunately Britney is safe and she was a stunning and happy bride," Rosengart said in a statement. The attorney also thanked the Ventura County Sheriff's Office and the sergeants and detectives involved in Alexander's arrest, and said he looks "forward to working with law enforcement to ensure Alexander is aggressively prosecuted and hopefully convicted, as he definitely should be." An Emergency Protective Order (EPO) is issued at the scene of the incident, and is granted "based on immediate concerns," according to the sheriff's office. An EPO expires after five to seven calendar days. Britney Spears; Jason Alexander.
