Britney Spears' ex-husband Jason Alexander was arrested Thursday at the Ventura County home

For 55 hours before the marriage was annulled in 2004, a Ventura County Sheriff's spokesman said

Spears' Thousand Oaks home was called around 2 p.m. by sheriff's deputies 

The official said Alexander, 40, was initially arrested for an outstanding felony warrant from 2016 out of Napa County

He was subsequently arrested in Ventura County on suspicion of misdemeanor battery, vandalism, and trespassing

A protective order was issued late Thursday requiring him to stay away from Spears, a spokesman said

In Napa County, the warrant was for grand theft and buying or receiving stolen property, sheriff's spokesman Henry Wofford said
