$20 million in cash was found by federal authorities inside a box spring in a Massachusetts apartment earlier this month.

U.S. Attorney tweeted out photos of the box spring stuffed with bricks of cash that were allegedly part of a pyramid scheme.

Authorities say the money was found in a Westborough, Mass. apartment and was linked to a pyramid scheme involving a company called TelexFree.

Homeland Security seized the cash in a raid that also led to the arrest of a 28-year-old Brazilian national named Cleber Rene Rizerio Rocha.

Rocha was arrested and charged with one count of conspiring to commit money laundering, which carries a maximum sentence of 20 years in prison.
