WOBURN, Mass. -- The half brother of comedian Dane Cook was ordered held on $3 million bail Wednesday after he pleaded not guilty to embezzling about $10 million from the entertainer.

Darryl McCauley, 43, of Wilmington was arraigned on charges including larceny, forgery and larceny by continuous scheme at Woburn District Court. Judge Joseph Jennings ordered McCauley to document the source of any funds used to meet his bail.

Prosecutors alleged that McCauley stole the money from Cook while being paid $12,500 a month to act as Cook's business manager as part of his company, Great Dane Enterprises, Inc.

Cook's attorney, Joseph Zwicker, described Cook as "very distraught" about the situation.

McCauley's attorney, Robert Goldstein, said his client is innocent.

"Mr. McCauley denies taking money from his brother without his consent," he said. "He's ready to confront these allegations."

Prosecutors accused McCauley of transferring funds from Cook's business accounts to his personal accounts between July 2007 and December 2008. In one instance, McCauley forged a $3 million check written from Cook's account to himself, investigators said.

McCauley allegedly used the money to buy four cars, and to take a seven-day trip across the country, during which he rented various cars. Prosecutors say investigators raided a Maine home McCauley owned and found $800,000 in cash in a safe.

Cook, 36, suspected his brother was stealing from him for some time, prosecutors said. He recently hired a new business manager in California and had been pressuring McCauley to hand over documents. Assistant Attorney General Rick Grundy said investigators were recently tipped off to the scheme by Cook's attorney.

Cook started his career as a comedian and his comedy album, "Retaliation," went double platinum. He has recently appeared in several films, including "My Best Friend's Girl" with Kate Hudson.
