Rihanna *If Rihanna isn’t careful, she could end up like John Lennon, says a New York City judge.

According to the Popdust.com, Judge Orlando Marrazzo ordered Kevin McGlynn to stay away from Rihanna‘s Manhattan apartment after he was caught “lurking” around the building. While handing down his order, Marrazzo compared McGlynn to Mark David Chapman, Lennon‘s killer.

Chapman gunned down The Beatles member outside his Manhattan home in broad daylight more than 30 years ago. That Lennon home, popdust mentioned, is located approximately 80 blocks from Rihanna’s current residence.

Court records show that McGlynn was allegedly caught on video surveillance on three separate occasions this month hand delivering threatening notes to an employee of Rihanna. The criminal complaint on the situation reveals that McGlynn “repeatedly called [Rihanna] a bitch,” and threatened to “bum (rush) in her apartment” in his letters. In addition, authorities claim that McGlynn sent at least four threatening letters to Rihanna’s home in California.

Judge Marrazzo went into further detail, saying McGlynn “wrote a series of notes to the singer that made references to murder and sexual assault,” in addition to accusing “Rihanna and other artists of using his material in their songs.”

The judge labeled McGlynn as a “ticking time bomb who is wholly fixated on [Rihanna] and poses a direct threat of serious physical harm or death to her and anyone around her.”

Reuters noted that McGlynn was found unfit to stand trial on stalking charges back in September—he was subsequently committed to a psych hospital in Staten Island, but has since filed a petition for release.

Judge Marrazzo made it known that McGlynn will be arrested if he goes anywhere near Rihanna’s home and barred him from contacting the singer via email, phone or written letter.
