Prosecutors say Rocha was part of a scheme to transfer millions of dollars to Brazil by laundering the cash through Hong Kong, AP reports.
It is alleged Rocha was handed a suitcase containing US$2.2 million at a restaurant before agents followed him to the address and later arrested him.
The money was allegedly from TelexFree, a defunct internet phone company authorities say was a massive pyramid scheme.
The Boston Herald reports that Rocha's lawyer argued that his client had no criminal record and should be granted bail with GPS monitoring.
