Former celebrity bodyguard Norman Oosterbroek protected several A-list stars during his career, but unfortunately he just couldn't defend himself. Authorities are investigating an altercation in which 43-year-old Oosterbroek -- former bodyguard to stars like Beyonce and Jay Z -- died after police Tasered him during a bizarre home invasion.

South Florida's NBC 6 reports that police were called when a naked Oosterbroek, owner of the security company RAD, entered a mansion uninvited on his street Tuesday, Sept. 3. Ooesterbroek and his family were apparently leasing a home in the same neighborhood. Homeowner Christiane Jung, 47, found Oosterbroek first and his intrusion eventually led to a violent confrontation between Oosterbroek and her husband, Markus Jung.

At the scene, Oosterbroke was also seen swallowing an unknown substance. When police arrived to try to take him into custody, he became aggressive, and had to be shocked by a Taser, according to the report. He was taken to a hospital and later pronounced dead. He was 43.

"It's possible that he may have been under some type of narcotics," Miami-Dade Police spokesman Detective Javier Baez said in a statement. "Again, he was observed swallowing, ingesting some kind of substance, unknown substance that is."

Other past clients of Oosterbroek include Lady Gaga and Rihanna.
