Police have busted a 53-year-old homeless man accused of stalking Rihanna and delivering threatening notes to her Manhattan residence, reports TMZ. Cops say they have surveillance video showing Kevin Mcglynn at the SoHo building three times this month alone, reports the Daily News. On the last visit, he reportedly dropped his benefits card, which led to his arrest. He allegedly gave the notes to a Rihanna employee and mailed others to the singer in California. “The nature of these letters (is) confusing," says an assistant DA. "They all do indicate a personal relationship ... that simply does not exist." Mcglynn, who during his arraignment accused Rihanna, Jay Z, and Kanye West of stealing from him, is being held without bail. (More Rihanna stories.)
