Fleetwood Mac guitarist Lindsey Buckingham was targeted in an alleged attack involving an “unknown substance”, with police investigating a woman they believe may be a stalker.
The 76-year-old musician was approached as he entered a building in Santa Monica on Wednesday, when a woman is said to have thrown a substance at him before fleeing the scene.
Officers from Santa Monica and Los Angeles police departments are now investigating the incident.
No arrests had been made as of Wednesday afternoon, though police said they have identified the woman involved.
Authorities added that Buckingham is understood to be familiar with her following previous incidents, according to NBC Los Angeles.
Investigators believe the suspect may have tracked his movements in advance, allowing her to confront him at the location. Buckingham was not injured.
Representatives for the musician have been contacted for comment.
The incident comes after earlier concerns over Buckingham’s safety. In 2024, he sought a permanent restraining order, saying he feared for his life due to a woman who had allegedly harassed his family since 2021.
A temporary order had previously required the individual to remain at least 100 yards away from Buckingham, his wife Kristen and their son William.
Court documents stated that the woman had obtained Kristen’s phone number and repeatedly called her, sometimes dozens of times a day.
Buckingham also alleged that she left lengthy messages containing threats and claims that she was his daughter.

In the filing, he said: “She also blamed me for facial deformities she apparently suffered as a child and demanded money.”
He added: “I do not know [the woman] and I am not her father.”
Police had warned the woman to cease contact in 2022, but Buckingham said the behaviour resumed in 2024, including a collage being left at his home featuring images of the woman’s face.
He also claimed she later appeared at one of his properties in Los Angeles.
It remains unclear whether Wednesday’s incident is connected to the earlier allegations.
Buckingham joined Fleetwood Mac in 1975 alongside Stevie Nicks, with the band going on to achieve global success with hits including Go Your Own Way and Rhiannon.
