Ne-Yo’s head is in danger. Seriously… this is no laughing matter.

Ne-Yo (aka Schaffer Smith) along with Sony honcho Clive Davis and Sony CFO Kevin Kelleher have all been reportedly threatened by a man who claims they released several songs ABOUT HIM without his permission.

According to court documents, a man by the name of Jeff Choi has been making deranged, escalating threats against the trio for months.

Choi is said to have sent hundreds of threatening emails, made dozens of angry phone calls and once appeared at Sony offices in person to complain, but was escorted out of the building after he became belligerent.

Dude even threatened to “shoot people in the head” unless Sony pays him $800,000. 😯

Details below:

Sony security contacted the FBI — which conducted its own investigation and decided to detain Choi for a psychiatric evaluation in August. He was eventually taken to a mental health facility, where he he continued to phone in threats to Sony execs. The FBI and federal prosecutors have now decided to prosecute Choi for making the threats.

Sony then filed for the restraining order against Choi — fearing he will make good on his threats when/if he is released from custody.

An L.A. County Superior Court judge granted the request — temporarily banning Choi from going near the Sony offices and requiring him to stay 100 yards away from Davis and Kelleher.

The court will determine whether to extend the restraining order on Sept. 28. (source)
