Kevin Mcglynn allegedly visited the star's home three times this month leaving threatening notes.
A homeless New York City man was arrested for stalking and harassing Rihanna.
According to TMZ, Kevin Mcglynn was allegedly caught on surveillance video three separate times this month delivering threatening notes to the singer's home.
The notes calling her derogatory names and threatening to enter her home were also allegedly sent to her California home.
On his third visit the man dropped his benefits card at the singer's Soho apartment building, making it easy for cops to track him down.
Mcglynn claimed in court that Jay Z and Kanye West stole his "material." He is currently being held without bail.
