20 More Charges Aimed at Dane Cook's Bro

Dane Cook's half brother has been indicted in Massachusetts on 20 additional counts of larceny ... for allegedly stealing more than $11 million from Cook over a nearly five-year period.

The new charges come on the heels of eight counts back in March -- where Middlesex County prosecutors say Darryl McCauley transferred company funds into his personal bank account.

Prosecutors allege McCauley embezzled the cash while acting as Cook's business manager between March '04 and Dec. '08.
