Waltham Man Convicted for Connection to Drug Ring

Tan Ngo will serve prison time for running an illegal gambling business in Boston.

A Waltham man convicted for operating an illegal gambling business in connection to money laundering for a drug ring in Boston’s Chinatown has been sentenced to 18 months in federal prison. 

A federal judge convicted Tan Ngo, 54, of Waltham, in connection with running an illegal gambling operating in Chinatown, according to an announcement from the U.S. Attorney Carmen Ortiz’s office.

This was not Ngo’s first time getting in trouble with federal authorities. An FBI affidavit says Ngo was a member of the Ping On gang in the 1980s and 1990s. Ngo served a federal prison sentence on charges that included heroin trafficking, according the announcement.
