EXCLUSIVE: Bank Sues Michael Jackson's Doctor Arnie Klein For $1 Million

Dr. Arnold Klein, Michael Jackson's dermatologist and close friend, is being sued for a million dollars, RadarOnline.com has learned.

Bank of America is taking the King of Pop’s long-time doctor to court, claiming breach of written agreement, unjust enrichment and indebtedness, among other allegations, in documents obtained by RadarOnline.com.

The lawsuit stems from a line of credit the high-profile Dr. Klein took out in July 2008.

According to the filing, "by terms of first agreement, Plaintiff provided Defendant with a revolving line of credit for $500,000."

Trouble arose in September 2009, when Klein missed a $100,000 payment that was due.
