BEL AIR—On Thursday, March 16, “Transformers” director Michael Bay, 52, contacted the Los Angeles Police Department to alert authorities that he suspected an intruder had broken into his Bel Air mansion.

Half a dozen LAPD squad cars arrived at the scene. Two police helicopters with searchlights circulated the 30,000-square-foot property. According to the New York Post’s Page Six, a resident of the neighborhood said that the police spent “some time” patrolling the area for the intruder, as Bay felt that he was in “imminent danger.”

Bay’s neighbors, who include business magnate Elon Musk and actresses Meg Ryan and Jennifer Aniston, were reportedly woken up by the disturbance. No evidence was discovered indicating an intruder broke into Bay’s home.

His call to police occurred a day after Kendall Jenner’s Hollywood Hills home was burglarized of $200,000 worth of jewelry on March 15. In recent weeks, other celebrities living in the hills of Los Angeles had their homes burglarized, including Jaime Pressly, Yasiel Puig, Derek Fisher, Nicki Minaj, and Alanis Morissette. Authorities have not disclosed if all the break-ins are linked.

The LAPD recently launched the San Fernando Valley Knock Knock Burglary Task Force, to target burglars who operate in high-end communities. The task force includes surveillance teams and undercover detectives to prevent such incidents.

Bay recently completed directing duties for the fifth installment of the “Transformers” film series, “Transformers: The Last Knight,” starring Mark Wahlberg, Stanley Tucci, Josh Duhamel, and Anthony Hopkins.
