John Mayer was the victim of a home burglary on Friday.
A thief or thieves broke a window to enter the Hollywood Hills house and made off with music equipment and other personal items worth an estimated $100,000 to $200,000, a police spokesperson told E! News. Mayer's security staff had noticed the window and called police around noon that day.
The 40-year-old musician was not home at the time. He has not commented.
No suspects have been identified.
Mayer had bought the lavish, more than 7,000-square-foot home from Adam Levine and wife Behati Prinsloo for more than $13 million earlier this year.
