According to TMZ, Taylor swift was called by police beacuse of disturbing song of a man out side her accomodation.
At the time she wasn't at home. The guards called for backup and when police and fire department officials arrived to the scene, law enforcement sources say the man was "disoriented" as he was handcuffed and seemed to be "emotionally disturbed".
Cops searched the duffel bag the man had in tow, but it contained nothing suspicious. However, he was taken to a nearby hospital for evaluation. It is unclear whether he made any threats or gained access to Swift's home, and he has not been charged. The incident marks the third time in three months a stranger has showed up at the pop star's home.
