According to the Ventura County Sheriff's Department, private security detained Jason Alexander shortly after 2 p.m. at the Spears' home, before the wedding. Deputies arrived soon after and arrested him for an outstanding warrant from Napa. 

Details of how he gained access to the property have not been released.
