Taylor Swift should be super secure in her $20 million fortified NYC penthouse, but it didn't stop an obsessed fan from wreaking some serious havoc.
29-year-old Mohammed Jaffar was hell-bent on getting a face-to-face with the singer, and according to legal docs obtained by the NY Post he was all over her building … in the lobby and on the roof.
He showed up multiple times over the last few months, hanging out on the roof one night between 10 PM and 2 AM.
He rang her doorbell incessantly … once for an hour straight.
Jarffar was arrested for stalking and burglary and he's being held on $20k bond.
The building is packed with celebs … including Orlando Bloom and Steven Soderbergh.
