Los Angeles police Lt. Brian Wendling says that employees inside the house in the Studio City area called police around 4 a.m. Saturday after the man came to the door and claimed to be a friend of the 19-year-old singer-actress.
Wendling says the suspect then repeatedly threw himself against an outside wall as if he was trying to break into the house. Cyrus was not home at the time.
The man, who was not identified, was arrested after officers saw him jump behind some bushes. He was carrying a pair of scissors.
Wendling says charges have not yet been filed.
