Los Angeles Lakers guard Lonzo Ball has severed ties with a co-founder of Big Baller Brand.

As reported by ESPN, Alan Foster has been terminated over concerns that the longtime Ball family friend has a criminal past and also can not fully account for a missing, roughly $1.5 million from Lonzo Ball’s business and personal accounts.

Ball stated to ESPN that he believes that Alan Foster, a friend of Lonzo’s father, LaVar, for almost a decade, allegedly “used his access to my business and personal finances to enrich himself. As a result, I have decided to sever all ties with Alan, effective immediately.”

Foster is also 16.3% owner of Big Baller Brand.

Foster, who served as the business manager over all of the Balls’ companies, including Big Baller Brand — which was formed as a limited liability company in 2014, developed a close personal friendship with the family when Lonzo and Foster’s son became friends in seventh-grade. According to LaVar, It was Foster, Lonzo’s father, LaVar Ball, has said, who helped convince him to create a shoe and apparel company featuring his three sons instead of allowing Lonzo to sign a multimillion-dollar endorsement deal, offered by more-established shoe companies like Nike, Under Armor and Adidas.

Sources close to the Ball family told ESPN that Lonzo expressed his concerns about Foster to his father several times over the past few months but deferred to LaVar to manage the situation.

It wasn’t until this week, the same sources said, that LaVar fully reviewed the email warnings and documents from Lukanga, as he had been traveling overseas with his younger sons in the fall. The sources described LaVar as “stunned” when the emails and documents were read to him. LaVar declined comment but issued a statement to ESPN calling the situation “devastating.”

“I’ve always believed in the best in people. Regretfully, I put my complete trust in Alan Foster to manage my son’s business affairs,” LaVar said. “At the end of the day, family comes first, and I support Zo wholeheartedly. Together, we will make this right.”
