Lindsey Buckingham attacked on street with 'unknown substance'

Fleetwood Mac's former guitarist and singer Lindsey Buckingham was attacked on Wednesday in Los Angeles.

Buckingham was entering a building in Santa Monica for an appointment when a woman reportedly threw an "unknown substance" at him and ran off, according to local TV station NBC4.

Police described the woman as a "stalking suspect", whom Buckingham knows from past incidents, the outlet reported.

The woman has since been identified, but no arrests have been made as of Wednesday morning.

Buckingham was reportedly not injured during the alleged attack, and the incident is under investigation.

A spokesperson for the Los Angeles Police Department told Us Weekly in a statement, "Our threat management unit is handling the investigation."

Buckingham became famous after joining Fleetwood Mac in 1974, alongside Mick Fleetwood, Stevie Nicks, Christine McVie and John McVie. (The band originally formed in 1967.) He was dating Nicks at the time, and the couple had an on-off relationship for five or more years.

Buckingham was featured on eight studio albums during his time with the band, including 1975's Fleetwood Mac, 1977's Rumours, 1979's Tusk, and 2003's Say You Will. He won two Grammy Awards with the group.

He was let go from the band in 2018 following tensions, specifically cited by Mick Fleetwood as a "brick wall" situation, and replaced by Mike Campbell and Neil Finn.
