California’s beaches are public, but on the sands of Malibu, one billionaire has been accused of stealing a slice of paradise — or at least a few scoops of it — for himself.

A lawsuit filed last week alleges that Mark Attanasio, billionaire businessman and owner of the Milwaukee Brewers baseball team, has been using excavators to dig up sand from Broad Beach and carry it back to his house as part of an ongoing construction project.

“This case is about a private property owner using a public beach as their own personal sandbox and the disturbing conversion of a public natural resource (i.e., sand from Broad Beach) for a nearby homeowner’s personal, private use,” the lawsuit says.
