Jacob Kulke was arrested at 1:45 AM after allegedly hopping a fence at the property. Kulke was detained by security and when police arrived, he told them he was the boyfriend of the homeowner.
According to reports, Kulke told police he had been in contact with someone at the home via social media and he came to town to celebrate Swift's birthday (which was Thursday). It is unclear if Taylor was home at the time.
Kulke was booked into jail and held on $10,000 bond.
Kulke has a criminal past -- TMZ has learned he was convicted of battery, disorderly conduct and drug possession in Wisconsin back in 2010. He was placed on 13 months probation.
